rear shock help! 97 850 177k

Well, apparently I screwed my car up. In removing the rear shock, I shear the mounting bolt at the bottom of the shock (I thought it was turning, it was not). What can I do about this? What needs to be repaired? I'm supposed to leave on a trip tomorrow morning.

Thanks,

Alex

I did the same thing. If you are lucky like me there was still a few threads left. Not enough for a proper Ny-Lock nut but just enough (2-3) for a regular nut to get a grip. I can't remember what size nut it is M10 or M12 maybe. I also used some Loctite to secure it because of the lack of thread. The Loctite will work wonders, blue or red will do. Good luck.

How badly marred are the bolt threads? Is there a pilot (starter) thread still on the bolt? Do you have access to a tap/die set?

Thanks, although I'm not sure if I have enough bolt left (maybe 1-2 threads). Does anyone know if it is possible to just replace the bolt or is it the whole link?

Sadly it is the whole link. We've had several folks on the various boards that have actually snapped the stud in half and I believe that the resolution each time was a new (used) trailing arm.

Lee, that's what I thought. Would a Volvo dealer even have that part or should I try and find a used part somewhere. Looks like I'm not leaving on my trip tomorrow morning.

I'm sure a dealer could get it for you but I think the next sounds will be <Gasp><Thud> when you get the price. List price is $608.48 per side.

If you have a good bone yard handy that is clearly an option but you will need an alignment after it is changed whether it is new or salvage. The rear wheel alignment is done with the bushing bolts that secure the trailing arms (Delta Links) together.

How bad was the old shock? If it was really horrible then the difference between not even having it bolted on and being there bad will be nill. It certainly won't be optimum but it might be the same as what you have been driving with anyway and salvage your trip.

Good luck,

...Lee

Just wanted to say thanks for all the help. I was able to get a nut on the sheared bolt with some loctite and it seems to be holding tight. Thank you all for the advice and to MVS for pics/insight/instructions.

When changing mine, I discovered that this had happened to mine at some point (I'm not the original owner) It had enough threads that it was able to be secured using a tapered head, lug nut. seems to work fine.
Since it's broken anyway, you could try cuttong off the broken bolt completerly, drilling it out, then welding a new bolt in place. I'd use at least a grade 5 bolt so it won't break.
since it's already broke, it's worth a shot.
One caution, be careful welding that close to the fuel tank!

cheers,
