Mercury 7T4Z-3A331-B Boot

When carrying out a shock absorber check, ensure that the car is parked on a smooth ground with its engine switched off and parking brakes kept in place while checking tire pressures. Press down at each quarter of the vehicle noting its body movement in anticipation for straightening after one or two rebounds; continuous bouncing back or unequal positions might mean eroded shock absorbers. Even though if considerable leakage is present we should replace them, they can be retained as long as there are no leaks when performing this test on the rest of the corners and examining for shocks' fluid leakage. The upper mounts should also be checked for wear or damage, confirming their firm attachment and subsequently replacing them where necessary. For steering and suspension examination, monitor tyre wear patterns, inflation rates as well as inspect universal joint, dust boots, steering gear housing, boot clamps, tie rod ends and any damage to all components of suspension and steering mechanism plus worn out bolts or rubber bushings. While an assistant turns the steering wheel check for easy movement without causing wear down or sticking during these findings. Move each control arm up and down to assess play in ball joints; remove those with play by replacing worn out ones. Walk around feeling the boot grease along with cracks which may have occurred therein. Behind look at suspension arm bushings for signs of decayed leaves. Still perform a CV Boot Check by washing them before closely examining them for signs of tear off/peelings/cracks and flimsy fasteners particularly concerning outer CV boot due to its regular movement in accordance with steering activity; if more than one crack is visible then it needs replacement because lubricant has leaked through outer CV boot hole.

If the CV joints are worn, which suggests that an overhaul is necessary, investigate all the alternatives available before starting the job as it may be useful to know that full rebuilt CV Boots are available on an exchange basis and will therefore prove quicker and less complicated. Some auto parts stores sell split type replacement boots that are easy to install without having to withdraw the CV Boot from the car, but should this be done we suggest that one pulls out the CV Boot and disassembles the CV joint to ensure that it is clean of contaminants that hasten wear. This would apply to any models with ABS check the sensor rings on the outer CV joints. Starting with the removal of the CV Boot followed by clamping of the axle in a vise with soft jaw. Lop off and eject the boot clamps and then draw the boot away from the inner CV joint and remove the joint housing to show the connection between the tri-pod and the outer race. Put a mark on the tri-pod and axleshaft using a center punch, in order to ensure reassembly is done properly, pull the ends of the stop-ring in order to free the retainer clip and remove it from the axleshaft. Hammer and brass punch out the tri-pod joint from the CV Boot without damaging the bearing surfaces of the metal. Scrub the outer race and the tri-pod bearing assembly for the old grease, check for wear if any that requires replacement. For reassembly, put the clamps and boot onto the axleshaft, cover the splines with tape so that they cannot mar the shaft. Replace a new stop-ring without fitting it into the groove, placing the tri-pod on the shaft and the arrow mark should align, fit a new bearing retainer clip. Use CV joint grease on the tri-pod assembly, the joint housing and on the boot, push the boot in to place, and balance the pressure inside. Tighten the boot clamps properly so that correct measures have to be taken for the same. In the same way, for the outer CV joint, remove the boot clamps, tap lightly on the CV joint housing to detach it, and clean all of them. That's why make sure to look for signs of wear and, if any, change the entire CV Boot assembly in its entirety. When refitting, fit a new sealing boot clamp and a sealing boot over the axleshaft, fit a new clip to the bearing of the outer CV joint and fill with grease. To ensure that the splines are correctly intermeshed, the CV joint is then slid over the axleshaft; after which, the boot is fitted before equalizing the pressure. Last but not the least secure the boot clamps and put the CV Boot back to its position. For AWD models, follow the basic procedure just discussed but for both the inner and outer CV joints, also use proper procedures for their boots while observing maximum care to enable the CV joints to function properly and for a long time.

To check the shock absorbers, park the vehicle on level ground, turn off the engine, and set the parking brake after ensuring proper tire pressures. Press one corner of the vehicle down and release it; see that its movement is stopped by coming back to level position within one or two bounces. If there is any continuing up-and-down motion or if it fails to return to the original position it may mean that the shock absorbers have become worn out or weak. Repeat this test in each of the remaining corners of your vehicle. Afterward, lift and support your car securely using jack stands then examine for signs of fluid leakage at their shock absorbers remembering that some light film is generally nothing serious but verify that any observed fluid leakages are from shocks and not elsewhere. Should leaking be noticed, replace all four shock absorbers as a set. Additionally, verify their secure mounting as well as check for any damage including upper mounts fitted on them. In case damage or wear is evident then four new shocks should be purchased together with replacing them as a set. To begin with during a steering and suspension inspection: inspect tires for abnormal wear patterns and correct inflation levels; look at universal joint between steering shaft and steering gear housing making sure no lubricant leaks out while also assuring yourself dust boots do not have broken clamps among other issues; examine tie-rod ends for excessive play while checking suspension and steering parts for any loose bolts plus fractured/dislodged units, deteriorated rubber bushings present within them all; with an assistant turning steering wheel observe if free travel exists anywhere in steering components noting chafing or binding especially where slackness becomes noticeable when they don't respond suitably to movement of control lever by hand; investigate ball joints ones at a time beginning by prying up then down against each lower control arm trying to detect play whereas if there's none this ball joint isn't worn out hence doesn't require replacement as part of control arm renewal; inspect the ball joint boots for damage and grease leakage. At the rear of your vehicle, look for any deterioration in suspension arm bushings. Lastly, know that CV Boot serves to protect constant velocity (CV) joints against contamination from dirt, water and other foreign materials. Wash the CV Boot with soap and water to avoid early damage by oil/grease. Inspect its surface for tears, cracks or loose clamps focusing mainly on outer CV boot since it wears out more quickly while following steering movement of front hub. The presence of any cracks or signs of leaking lubricant means immediate replacement is required so as to maintain integrity of CV joints.

If CV joints are worn, you need to consider an overhaul, because there are, apparently, only full rebuilt CV Boots to be purchased on an exchange basis to save time. The CV Boots have the ABS sensor rings installed on the outer CV joint and therefore check for any chipped or missing teeth on them. First of all, you should take out the CV Boot from your vehicle and then fix it into a vise - the jaws of the vise should be saturated with wood or some kind of cloth for better protection to the CV Boot. Outboard CV joint is fixed and the outboard boot can be replaced only when the inboard CV joint of the joint is dismantled. I took off the boot clamps and then the retainer clip I pulled the boot back from the inner CV joint and then noted the relationship of the tri-pod to the outer housing. Take special care not to cause the bearings to drop off the tri-pod as you make separation of the joint housing from the CV Boot. That involves removing the retaining clip and using puller to pull the tri-pod off the shaft, as well as pulling out the old in-board boot. The outer CV joint boot can be had by simply removing the two boot clamps that hold it in position on the shaft and sliding it to the inboard end of the shaft. Remove the old grease from the outer race and tri-pod bearing assembly and wash with solvent, separate the parts before washing as they cannot be interchanged, wash the needle bearings with solvent. On the rollers, tri-pod, bearings, and the outer race, search for any wear that will call for a replacement of the inner CV joint. For reassembly, if replacing the outboard CV joint boot, it is required to slide a new boot on to the shaft, pack half the grease from the sealing boot kit in to the outboard CV joint and spread the remaining grease in the sealing boot. Place the small end of the outboard boot to the groove of the axleshaft and compress the boot clamps. Place a new inboard boot clamp and the inboard sealing boot over the axleshaft and then place the tri-pod with roller bearing over the axle shaft then install the new snap ring that should not come off; it drops down. Put half the grease into the bearing and distribute the other half inside the boot, after which place the outer housing over the bearing assembly and fasten the outer bearing retainer. Place the large end of the boot into the groove of the outer housing, slide two boot clamps onto the boot but do not tighten and pump the boot to the same pressure as the outer race by inserting the flat end of a small, dull screwdriver between the boot and the outer race. Last of all secure the boot clamps with the appropriate technique applicable to the type of clamp used, then fit the CV Boot. When it comes to AWD models the process is quite the same as when working with RHD: it starts with taking the CV Boot out of the car and fixing it in the vise. Take out the balls and bearing cage, then take off the boots inboard boot, pull back the boot cover and throw the clamps and retaining ring of the outer housing away. Pull the retaining clip away from the axle splines, take off the boot and also the outer CV joint boot. Wash all parts carefully and look for the signs of wear that would imply that the whole CV Boot should be changed. The same applies to the reassembly process where grease should be applied on the outboard CV joint and its sealing boot, the boots should be properly seated and the clamps well tightened before the retaining clip of the inboard end can be fitted back and the CV Boot reinstalled.

First, you will have to remove the axle from the car and secure it in a bench vise. Remove the CV Boot clamps, and retainer clip, and then pull the CV Boot back off of the inner CV joint. Separate the joint housing from the axle and remove the tripod and old inboard CV Boot. The outer boot can be slid off by removing two boot clamps. Inspect components for wear and clean them. Next slide a new boot over the shaft, pack grease into the outboard CV joint, and spread the remaining in the sealing boot. For rear-drive axles on AWD models, proceed similarly as for front-drive models above.
