Hey everytime i go to slow down from a considerable speed (65+) my car starts shimmying pretty intensely. I was just at Chrysler Service Department the other day and they said my brake pads were fine but I thought it might be the rims so i asked them to make sure they were tightened and they said they were on there fine. I didn't even bother asking the Service Department, because their first response would be that its the fault of the rims. I dont neccesarily have to get on the brakes to make the car start shaking, as a matter of a fact it seems they dont seem to shake as much when i slam on the brakes.

You guys have any ideas what the problem might be?

It may be the tires. Have them checked, maybe it needs balancing.

Likely to be balancing. I'm having the same issue, and I know for a fact that my front tires need to be balanced desperately.

I just had mine fixed with similar issue, more towards the breaking side though. Turns out my front rotors were warped. May want the have them checked just in case.

Yeah i was thinking that could be the problem...how much did that end up running you and did you have Chrysler do it?

I had a local mechanic I know do the work. Labor cost was $40.00 and I think the rotors were around $80 each. Quite reasonable I thought.

Not bad at all, when i get back from vacation i'll take it to a brake specialist. Thanks for the help.

I don't think a brake specialist is what you need here, since you're getting shimmy simply by lifting off the throttle, rather than when braking. This sounds more like a wheel and tire issue. I'm pretty sure you have a rotating imbalance. I would have your front wheels checked by a shop with good balancing equipment, like a Hunter GSP9700.

Hey guys, I don't think the problem is related to wheel and tires at all. I have a 2006 300C with 44k miles. I never have any problems with brakes, tires or wheels except under very unique conditions as follow: 1) Rain, 2) Downhill, 3) 65+mph. I get what I would describe by Jeep drivers as front end "death wobble". It seems like there is a mode or event that kicks off strange ABS behavior caused by light brake pressure at high speed...in my two cases...months apart. The dealer had my car for two days and could not find anything that would cause this weird "front end wobble". In all other situations I have ZERO steering wheel vibration or shake or any sense of shimmy any other time. 'Just my thoughts. Comments?

Check your tie rods and other suspension components get the alignment of all 4 tires checked, check the balancing of the rims and pray to god you dont have what i did broken drive shaft bolts..... i ended up grenading my whole drive line. goodluck!

I have never seen this mentioned before, but tire slip is a possibility.
Tire slip is caused by too much lubrication being applied to the tire, which causes the tire to slip on the rim.
The way to check for tire slip is to place a mark on the tire and rim with chalk, or some other marker, and see if the marks move apart.
