Generally, if you lift the wheel where you suspect a bad ball joint, and stick a crowbar between the tire and the ground, you should be able to detect up and down play if the ball joint is shot. If that feels solid its pretty safe to say the.joint is doing its job.
how do you replace ball joints on a 2000 envoy
Yes, it can
Put the car on a rack and have the ball joints inspected by a professional if you suspect they are bad. Your car will dart from side to side and handle poorly if they are bad. This is a very dangerous situation so have this looked at ASAP.
BAD BALL JOINTS instuctions
they can be because your ball joint is the key to your steering and suspension if the ball joint goes that can be very bad
Ball joints only really need to replaced when they are going bad. Usually you can tell if you put one hand on the 12 oclock position and the other on the 6 oclock position and try to wiggle the the tire. If it wiggles this way then ball joints are going bad. (Jack the vehicle up first). If you put one hand on the 3 oclock and the other in the 9 oclock position and wiggle it and it moves then the tie rods are going bad. If the whole tire moves in and out then the bearings are usually going bad. Hope this helps.
Dry ball joints/suspension joints. Universal joints going bad. Worn brake pad "squealers".
Bad shocks, ball joints bad, tires out of balance. More then likely shocks.
replace when bad
If you have a factory steering knuckle, ford designed them for the ball joints to not be removable. If you are thinking that your ball joints are bad for some reason, you will need to get after market steering knuckles, and ball joints for replacement. Costly, I know but worth it. I suggest MOOG, I've always have had good experience with them.
Low air pressure, hitting curbs, bad ball joints, bad alignment.
