    97 Deville "clunk" over bumps in the front

    Hello gentlemen, just got my 97 Deville on the road, 81,000 miles.
    It passed the safety inspection for the front end, BUT , when going over bumps I hear a clunk in the front end, much like going over train tracks.
    Wondering if you guys think this is worn struts ???
    Thanks, Bob

    Sway bar bushings or end link bushings maybe.

    Indeed take Rangers advice... a lot of struts and other suspension components are replaced in many vehicles and the problem is as simple as sway bar bushings and/or end links... and ironically those are typically the easiest and cheapest to replace.

    I have a 94 Deville(Generally the same body), I have replaced all of the chassis parts from the Struts to the ball joints(Includings the Swaybar End links), And I still get the same noise that you describe! I am not sure, Of course your noise my be different than mine, but I just figured I would let ya know. There isn't a bushing or chassis part I haven't replaced on my car! I still get that noise though! It bothers the heck out of me! Anyone have any other suggestions?

    i had the same symptoms on my '97 last summer, found sway bar end links were bad. easy to find, lift front of car turn wheels reach inside behind wheels and give links a good tug, you'll know if they are bad.

    Just curious, did you replace the bearing plates above the struts? My fathers '99 Deville had a mysterious clunk in the front end, especially when the wheel was turned and that is what we found.

    I have a clunking sound coming from the front suspension too. The bushings and rubber boots look fine. I have no idea where the noise is coming from.

    I Replaced the Entire lower control arm as a whole. I got it from my work... Its came with bushings all all... It was also easier than drilling out the Factory ball joints... it came with ones that are bolt on for easy R/R... Anyway, In My opinion... I would. But thats me...
