S80 popping noise is left front

Postby Mikey » Sun Nov 20, 2005 4:02 am

My 2000 S80 just had new struts, strut plates and bushings replaced, but I still have a popping noise in the left front when I put a strain on the left front such as going right in to a sharp corner and pops a little after I straighten up from the corner. What else could be popping?? Any help or suggetions would be appreciated.

How 'bout the stab links?

Postby Chapstick » Mon Nov 21, 2005 3:22 am

Hey, did you check the end play on the stabilizer links (rods)? They connect the anti-sway bar to the struts. Also, they may not be bad, but with your new "other" parts, the ride height may be affecting their travel. Not necessarily a need to replace anything, just a little noisey under suspension "flexing" on turns.

I have the same problem that I can't figure out. Had the car to two different Volvo dealers and one mechanic with a very good reputation for suspensions in my area. None of them could find a problem with the suspension. Only thing abnormal was some tire rub on the inner wheel well passenger side. Changed the turn stops which didn't fix the popping sound.

S80 popping noise in left front

Postby Mikey » Mon Nov 21, 2005 10:22 pm

Chapstick-- I had replaced the stabilizer link on the right cause it was bad, but put the old one back on the left. Everything is new on the front except the one stab. link and the one strut bushing on the left which I just bought today and I am going to have it put on tommorow. If this doesn't stop it I'm going to go crazy. These little things drive me nuts! :x The thing is, it wasn't doing this on the left side when I took it in, I took it in for the right side bushing was wore out and popping, now it's fixed and the left is now popping. What do you think??

Couples are the ticket

Unfortunately, a late model Volvo like the S80 can be finicky. There's something to the old adage of if there's a left and a right, do it in pairs. I've had limited success in getting by with changing "the affected" part without having the other side scream for attention. That might be the case with your setup. I do know that the strut mounts (struts, too) need to be changed at the same time frame. The links aren't as critical. The bright side is that everything will be new under there. Or you could invest in some good earplugs... Good luck.

Just had the left side strut link and bushing replaced and the damn thing is still popping clearly on the left side while cornering or putting a strain on it. Other than ear plugs, any other suggestions?? The only other parts to replace is the A arm, stabilizer bar, or motor mounts. :?

I can suggest a couple of things:
If you have access to a large floor jack, elevate the front end off the ground. Exercise all necessary safety precautions! The objective is to take the "suspension" parts out of play as much as possible. With the car safely supported and the front end raised (the tires on both sides have clearance to rotate without touching the ground. Start the car and turn the steering so that it rotates from rack to rack. The best case would be with both wheels removed and someone else at the steering wheel, so that you could inspect for noises. Is the popping noise detected?
If so, let us know. We'll go from there. What this will eliminate is if the links are "folding over" when you turn from end to end or if the steering limiter bushings are worn and generating the noise.

The A-arm has two bushings and at the end of the "A" is the ball joint. Usually, only the front bushing will need replacement. You can inspect that by examing the rubber "webbing" around the center stay. If it's worn, there will be lateral movement that COULD cause noise on turns. By it's highly unlikely that it would be very loud.

I jacked the car up like you said and turned the wheel from left to right with no noises at all, now what???

What haven't you replaced?

Postby Chapstick » Sat Nov 26, 2005 3:16 pm

It seems like you've covered all the parts that contribute to those noises from the suspension. The anti-sway bar has rubber bushings that fasten it to the cradle that could be worn out, but that's just a guess. When the struts/bushings were being replaced, did anything get misaligned (coil spring seating, etc); were the bushing fasteners (the little "+" nut that compresses the bushings) tightened all the way down? I really don't have any other suggestions. Anyone else here with an idea to help him?

I'm taking it to the Volvo Dealer Tuesday and they are going to check it out for me and hopefully fix it. At this point, money is almost not an object. I will let everyone know what they find out just in case someone else runs into this. Thanks for your help Chapstick!
