To check the shock absorber, the vehicle must be parked on an even ground and then engine turned off; parking brake should also be set while tire pressures are checked. Push down on each corner of the vehicle and release; watch its movement for it to settle back after one or two bounces then rest in a level position; if it keeps moving more than that, old or weak shock absorbers might be responsible. This test is repeated for every corner of the car. Raise and safely support the vehicle with jack stands before examining all shocks for fluid leakage so as to see if the fluid is from there or some other source. If there is a leak you can replace them. Also, confirm that they are solidly mounted and without damage by checking wear or damage in their upper mounts and if necessary, change them as a group. Start by looking at tire wear patterns and inflation pressure to get an overall picture of steering and suspension health. Check for oil seepage between steering shaft universal joint and steering gear housing, confirming intact dust boots and secure boot clamps. Play in tie-rod ends needs to be checked while all suspension parts have their bolts secured alongside any broken connectors or dislodged parts as well as spoilt rubber bushes throughout both systems where needed. Check all steering components during an assistant's turn of the steering wheel for smoothness, rubbing, binding; mark areas with considerable slackness here. To check balljoint wear attempt prying up control arms alternatively followed by replacing any worn-out ball joints found this way. Test such boots for damages plus loss of grease therein as well as worn-out ball-joints which ought to be replaced any time they are detected here using a prybar moving up & down each control arm; inspect balljoint boots for damage particularly cracks & leaking grease inside cv-joint covers at rear end suspension arm bushings inspection cv-boot check know that these boots protect cv-joints thus they should be washed with water & soap, so that they can resist oil and grease attack. Ensure you inspect them for tears, cracks and loose clamps more especially the outer CV boot, anything wrong or leaking lubricant calls for an immediate replacement.
