shock absorber test xc70 2001

Post by darrylrobert »

I have been hearing some faint hollow thumping sounds coming from my front suspension, so i checked it and found the cross (holy) nut was loose. this loose nut allows for movement/noise within the strut.the rubber upper seat was in good condition. I checked the absorber and found it also wasnt perfoming well, compared to my spare the resistance compressing was similar but it would only uncompress half way by itself, my spare uncompressed fully by itself. The shaft also had some latteral play and made some gurgling oil noises compared to my spare which had no play and made no noises.

You can find the exact genuine replacement code on the metal plate on your car - of course, all aftermarket parts are the same, while Volvo has many different numbers (also see the video description)
As for the shocks, I had quite a few new and older, and can say that while the rod must come back fully and quite quickly, it doesn't always mean the shock is completely worn. I would say, if it doesn't leak, it doesn't ride too harsh on poor pavement, and it still bounces fine when pressing down on the car corner, I would keep it. I had to replace my original ones because they were riding really harsh on our poor roads, but if the roads were better I would have kept them. Speaking of the cross nut, it is quite hard to tighten it down because of the shape and because it sits against the rubber of the spring seat. So it doesn't need much force, just needs to be installed with the cross at the top, and not at the bottom - the cross has to sit against the top metal washer
