Do you have good quality jackstands and a good floor jack ? Air compressor, good gauge ? Basic tools like1/2 " drive sockets and ratchet? Breaker bar ? A medium to large ball pein hammer ? Long pry bar ?
Some of the wandering around is one of the quirks of this suspension.
To make sure that the front suspension parts are in safe condition, we need to get the front end up in the air. Block the rear tires, put jack stands under the subframe and put the parking brake on. I know that this is very basic but others are also reading this thread and some of them may be just getting into working on their cars and need basic instruction on safety procedures. First thing is to inspect the tires for excess wear, bubbles or tread damage . Next is the air pressure. Under inflated can cause the front end to feel very sloppy. Over inflation cause the tires to wander all over the road. All of the tires need to be inflated to the proper pressure. How much will depend on the tire and rim size. Inspect the front end parts for damage, loose parts, missing cotter pins and/or nuts. Worn or missing rubber in the bushings. Excessive play in the front end. With tires still installed, Take one side and hold the tire at the 9 o'clock and 3 o'clock position. Turn the l/f tire and turn the tire to the extreme left and then work the tire back and forth checking for loose parts. Go to the other side and do the same thing again. One of the common front suspension parts to wear out is the idler arm. See if it has any up and down movement when you rock the tires back and forth. If the front suspension is over 10 years old, you are probably going to need to do a suspension rebuild. One of our sites' sponsors is P-S-T. They sell excellent quality products and all different stages of front suspension packages. If you want more detail inspecting and repairing the front end, there are many sites on You Tube you can use for reference.
