Just noticed today one of the studs on my new Donahoes is sheared off.

How does this happen ??? the shock is only 4 months old. :pat:

 

My guess? Too much make-up torque during assembly (manufacturer) causing the stud to have either tensile or torsional failure. Basically like over torquing a bolt and snapping the head off of it, only in this case, it was torqued just enough to stay together but still cause a stress fracture that eventually completely failed. If you could post a pic more of a top view looking down at what's left of the stud it'd be easier to diagnose.

 

how long can I get by with just the two bolts????

 

Looks like it was overtightened during installation, it would be quite easy to remove the broken stud, but you'll have to remove thw coilover assemble to gain access.

As long as your not taking it offroad, the 2 remaining blots will hold it in place.

 

Will I be able to just replace that stud or will I have to get a new top for the coilover ???? Heres a better pic.

 

Oh. I thought you were talking about a center bolt, like at the end of the piston rod or something.

I wouldn't worry about it much but just fix it ASAP. Like Bruce says, don't wheel with it like that.

 

what would be the easiest fix. I have contacted Donahoe but have not recieved a response back. can I just repace that stud or do I need a whole new piece????

 

If the 2 in place are good, then you are okay for now, but how do you know they are okay? Just playing the devil's advocate.

 

I dont, what would be the easiest fix. I have contacted Donahoe but have not recieved a response back. can I just repace that stud or do I need a whole new piece????

 

jsut replace the stud... all you need to do is pull the shock out, go to the hardware store and match the stud.....

 

It sounds simple and hopefully it is, but this is a male stud inserted in to a top plate Im not sure how you get it out. it does not go through the plate.

 

Two ways to remove that broken stud, first use vice grips to unscrew the stud out of the top plate. If you have a welder lay a nut on top of the stud and weld it, then simply unscrew it out.
