At my wits end!!
 

Hi All! I am new to this forum thing but figure somebody out there alot smarter than me can hopefully make some suggestions - or better yet - have dealt with the same problem!
My 2005 Deville's front end wobbles upon acceleration. I went up a hill the other day and the car was wobbling like crazy! - also does it on flat areas too. The wobble seems worst at around 68 mph
Have had it at the dealer 3 times. They have rotated, balanced tires, aligned and hooked it up to the machine and everything checks out - It was suggested that it may be something electrical - having to do with some coils???
Anybody got any ideas?? It has gotten worse over the last year (I've only had it slightly longer than that) I used to love driving it and now dread it.

Would appreciate any help-- Thanks!

ok can u describe the wobble
left side right side
does it happen above 68
or less then
have u checked your rims for dents
do u have another set of tires and rims

This sounds a bit wierd to me. i would almost be certain its a wheel or tire issue. i had this issue due to unbalanced tires. Aslo if your rim is bent this may also happen most noticeable at HIGHER speeds. Otherwise a possibility would be a wheel bearing issue or brake rotors. i would try a wheel and tire shop not a dealership. Dealerships to me are not worth the money for the work they do.

Maybe a broken belt in the tire?

just saw a deville the other day where the rack and pinion was loose, don't know if it would make the front end wobble. i have seen tie rods and wheel balancing make the front end shake. maybe switch mechanics.
