    The steering wheel seems to exhibit two issues:

    1) Shaking fast at highway speeds
    2) Slowley rocking right to left at highway speeds (kind of loping)

    Let me know if this info. helps. Thanks!
    From what you are describing it sounds like just your steering wheel is shaking while driving, correct? If this is true you may want to check your steering linkage. It is possible that something is loose and that is causing the vibration. My father-in-law had this issue with his 1929 Ford Sedan (LT1 engine in it LOL!!!). We couldn't understand why his steering wheel would shake while he drove and then we checked the linkage for the steering and almost all of it was loose. Once we tightened everything up it was all good. Just a thought. I really hope you get this solved so you can enhoy your ride again man.

    Loading changes the vibration.... Let's get the car back to the Pedders shop and double check the wheel hubs (bad bearing in one?), tie rod ends and ball joints. Are you working with Victory or Backstreet?

    You dont have some cheap ass tires on there do you? Some of the cheaper tires are out of round and it changes as they heat/cool and will make you crazy....

    When you take the car to Pedders, have them check the steering rack for tightness. You stated the vibs subside a bit when you corner. This makes the rack a suspect, especially where gforces through the turn will shift the rack to one side and then the other, thereby tightening it and subsequently halting the vibration momentarily.

    If not the rack, check other fittings for correct tightness. Keep in mind the rack bolts must be very tight. Like full impact from a 1/2" impact wrench tight.

    Pete - I took her to Victory. I'll get her back in there next week and have them give you a call.

    Sarge - I have a set of KUHMO's on her. They are Max. Performance Summer Tires and are not cheap ($145 ea.). This is my 3rd set of these tires on various performance cars and I have never had this issue. Besides, the shake also orrurec with the OEM BFG's on her so it's not a tire issue.

    Subscribed.. I am having the same exact problem. Mine has a slight vibration all the time.
    I get steering wheel shake from around 55mph sometimes. The only difference is mine seems to go away at 73-78mph. This threads got me thinking, my suspension/tires/wheels/brakes are all OE. I did lower and disconnect the steering rack when I installed long tube headers. Going out to check those bolts now.

    Pete - I am not that impressed by Victory's service. They had a couple of 25 year old kids look at my car and of course they did not find anything wrong with it. I don't believe that they even checked the wheel hubs. I did check them myself with a dial indicatior and they seemed OK (within spec.). My insurance company has sent me to another shop. My point is that I am not into wasting time. Do you really think that it's worth the time to take my car to Victory or should I just take it to the shop that my ins. company recomended?

    Did you try tightening the rack yet?

    Are you telling me to tighten the steering rack? If so, how/where?

    Yes, the rack may be loose. The rack is attached by two larger bolts. One bolt attaches the rack to the left frame rail and the other to the right. The tie rod ends then attach to spindles. So, there are only two attachment points which hold the rack in place.

    If the bolts are loose, this causes all sorts of vibrations, steering wheel pull, or other erratic behavior. Hence, my suggestion to check rack tightness. It is easy to check and may save you a lot of time, money, and grief in solving the problem.

    Hi all,
    I read (I think on another forum) about these cars accumulating crap between the wheel and the hub's flange. IIRC, guys were removing the front wheels, cleaning the hubs, and the inside of the wheels where they mate. Then, they were re-clocking the wheels (in other words being sure they weren't installed with the same studs in the same holes as before) and it solved the same problem. My '04 is doing it now...and everything else appears tight.

    Surfinjoe,

    Did you ever determine the cause of the vibration?

    If so, how did you correct it?

    Thanks,
    Patrick

    OK, so you all won't believe it but I just got the shake fixed this weekend. After rebuilding the front suspension, checking everything, taking the fucking rims, calipers and hubs off something like 20 times, hand torquing everything every time, checking the hubs on-vehicle with a dial indicator 5 times, new tires, a new rim, two 4-wheel alignments, a cradle alignment, 3 trips to my worthless Pedders dealer (no offense to Pedders) and countless trips to shops telling 'Uh, we don't know how to work on them there foreign cars' I finally found the cause of the shake:

    My 4 'NEW' tires were all out of balance and I had one bent rim. Yup, that was the cause of my fucking shake. I am not saying that there were not a few other things that contributed to the shake, but in the end that was the problem.

    Even the Pontiac dealer couldn't fix it. I had to go to my trusted mechanic (Campbell/Gardenia Service Center In Lovely Royal Oak, MI) with their low tech tools to diagnose a problem that no one else could (Including Bell tire and their supposed "Road Force Balance"). The mechanic/owner put each tire/rim on a fixture and 'spun' them to check for trueness. He then held a china mark pencil to the rim to mark any high/low spots. He did find that my tires were a couple of MM out of round, but said that it was most likely due to the car sitting for so long and my soft-ass MAX PERFORMANCE TIRES. He then told me that each wheel was 2-4 ounces out of balance and visually showed me the bent rim (flat spot).

    The rim is still bent (just ordered another set of rims) but now that the tires are all in balance the shake is 90% gone. Once I get my new rims, should be 100%. Thanks to all who helped!

    Wow. Good to see you're close to getting rid of your shake.

    Balance your tires dude. If it's there and goes away after speed change it;s in the balance of the tire.

    And beware of the local 'Tire Stores' and their road force balance. Just a bunch of BS and a waste of time/money.

    The problem with MOST tire shops is UNTRAINED idiots doing the labor. Almost ALL balancers require calibration from time to time which they usually NEVER receive.

    Glad you finally got rid of the issue though sorry it took soooo long and cost soooo much.
