Hello, I have a77 Deville, it drifts from side to side when driving down the hwy. I replaced the center link and a tie rod on the right side, it helped for about a week or so. Nice and tight now its back to wandering and drifting back and forth like a drunk sailor. Any help would be great. I am also having a problem fining a good used light blue steering wheel, dash pad, armrest and the plastic wood grain around the switches for my 77 deville. thanks again John

Have your "toe-in" checked now that you've replaced those parts. If you're toed-out it would do that

It was allined after and I was told it was fine.

Do your tires squeal around turns? I had "glazed" tires on my fronts and the car was all over the road. How about the sway bars? I don't know if this could cause it, just suggesting. You can add the rear one if you don't have it already. They're pretty easy to find in a junk yard and they should work all the way up to the mid 90's rwd cars.

I have new tires, and sway bars front and rear, on an on ramp to a hwy( a tight clove leaf) the steering jerks at a serten point. I dont think it should do that? I can get it to do it other times to but it more comon then. It wanders at all speeds not just on hwy.

I had that problem on my '96. My mechanics replaced all tie rod ends (at my request, not up-sell) and adjusted the toe-in. That fixed it.
