As with anything you do on the undercarage of autos, be sure to use jackstands and work on level ground. The castlenut needs to be backed off to free the lower part of the balljoint, and then you have to get the stem out of the seat of the nuckle. Most people use a "pickle fork" type tool that straddles the stem of the balljoint, and it is driven in to "pop" out the stem from the nuckle. This tool is like a wedge. This will most likely ruin the balljoint, as it will probally tear the rubber boot, but you said its already bad anyway. If you need to take the joint apart for some reason and not ruin it, what most pros do, is hammer on the nuckle sideways. Believe it or not a few good wacks on the nuckle will usually dislodge the stem from the nuckle with no damage to the stem. If the ball joints are of the rivited in type, you will have to use a grinder to take off the heads of the rivits. Be careful not to grind into the "A" arm. Then you can drill out the remaining rivits. Sometimes you can drive out the remaining rivit pieces with a hammer and punch, but usually it takes the drill method. The new balljoints will bolt in where the old rivits were.
ball joints cannot be tightened. if they re worn and have play in them, they need to be replaced
You can't repair worn out ball joints. Replace them with new ones.
Jack the truck up till the wheels are off the ground. Grab the tire at the top and bottom and see if it moves in and out. If it does, that means the ball joints are worn. If you do this on the sides and there is movement, it means tierods or something in the steering lickage is worn. Same procedure on any vehicle.
To do so would be a waste of money, replace the upper ball joints first, then have it aligned.
Worn ball joints, worn tie rod ends and worn shocks are the main causes.
Dry ball joints/suspension joints. Universal joints going bad. Worn brake pad "squealers".
worn suspension (ie), ball joints , tie rod ends also possibly cv joint wear but most likely ball joints worn your answer here...
slight knock when turning can be caused by a loose wheel bearing,worn ball joints,or ball joints that need grease,can also be caused by a worn bearing in side the steering column,or worn out shock absorber.
That depends on when it shakes. Low speed, it could be a bad tire, bent wheel... High speed, it could be a bad tire, bent wheel, out of balance wheel, worn ball joints, worn tie rod ends, worn idler arm...
Could be worn ball joints, worn steering linkages, worn/out of adjustment steering box and or worn/out of adjustment wheel bearings.
Wheel shaking is caused by a balance problem, either a tire needs to be balanced, a wheel is bent or there is a problem with an axle. HOWEVER! Most vehicles can tolerate a tire/wheel that is a LITTLE out of balance provided that everything is functioning properly. Among the list of things that must be functioning properly are the ball joints. Worn ball joints make the front end loose and the vehicle does not handle properly. If you suspect worn ball joints, replace them.
Bad shocks, worn ball joints, worn tie rod ends - all cause tire wear.
