Car shimmys when driving at around 40 Miles Per Hr?
 

Hi,

I recently aquired a 1982 380 SEL, and it is in excellent condition with only about 75,000 miles.

I have noticed that from time to time the back right side of the car shakes and shimmys a bit usually within the first ten minutes after driving the car from a cold start. It doesnt shake at all during excelleration and then starts in at about 40 Miles per hour. As the car slows down it shakes a lot and feels as if there is a bulge in back right tire....When it does this, it really feels like the back tire is elliptical especially as I decellerate down to a few Miles per hour, as I accelerate from a stop light it stops untill that 40 MPH point, and then starts shaking again untill I completely stop........After about five minutes of this, the shaking stops completely and the car drives fine, no shaking what so ever can be felt.

Does anyone have any idea on what this problem might be? Is there some sort of component that could cause this problem, that switches off after the car heats up or something?

P.S. The car has been sitting more or less for about a year with no street use what so ever, not sure if this makes a difference with my problem, but thought Id mention this as well.

Please help!

P.P.S. I am in the process of changing all of the cars fluids, plugs, wires, and distributer, and various filters.....Is there anything else that I might want to change or check since it sat without use for so long?

Thanks

Erik

Possible causes:
Delaminated tire, out of round or unbalanced wheel, bent wheel, drive shaft (U-joint or flex disks), rear suspension bushings, rear half-shafts.

I just had my tie rods replaced...my car did the exact same thing ;)

How much?
 

How much did changing the tie rods cost? I have a similar problem and have been told to get an alignment after trying other things...
