So I'm working on replacing my shocks and I can't get any wrench or tool to hold it in place while I'm trying to remove the top nut. Would it be best to just take the tower off and hold the shock with a vice to remove it?

 

Do you have a Dremel with a cutting wheel? If so, you can cut the nut enough it will weaken/loosen and then pop right off. A cutoff wheel works as well if there's enough room.

 

Didn't even think of that. I have an angle grinder with some cutting discs.

 

If you are definitely replacing the shocks, you can clamp down the shock rod with a pair of Vise-Grips to hold it in place (keep it from spinning) while removing the nut. A bit of PB Blaster on the nut and threads will help make removal even easier.

 

Definitely replacing them. I have 4 new ones that have been sitting in my garage for 2 weeks while I've been trying to get that nut off in my spare time.

 

Like posted above I took a cut off wheel and cut the protruding stud flush with the bolt and hit it with the impact and came right off. Now if the only my rears
were that easy.

 

Always use Anti-seize the threads (and even the shaft) of fasteners. Adjust all torque values about +20% to compensate.

 

I just cut it off with a sawzall right below the nut.

I know have an impact gun

 

I'll take the whole tower off and then cut it. That'll work! Then I'll have some room.

 

I've used the vise grips and impact gun, they come right off.
