One of my front JIC strut cartridges is stuck and will not thread up or down in the bottom of the coilover. I tried to thread it down via the threaded nut that the spring sits on since it tightens down on the second threaded nut and should turn the whole assembly but it will not budge. PB blaster didn't help either.

I did notice a hex just past the adjustment **** on the bottom of the strut cartridge. Is that what this hex is for?
I just wanted to make sure since it's a pain in the ***** to get to with the axle in the way.

 

Try mixing up some ATF and acetone in a 50/50 mix and try to get the mix down in the threads and let it sit for a few hours. That's what I did on my front KSport's.

 

Oh and be sure not to get that mix on plastic or rubber.

 

yea thats a good method. Just dont mess the threads up hammering the collars

 

Yeah I'm not the type to use a hammer on JICs.

 

You can throw a wrench on the collar and hammer the end of the wrench.

 

Just went through the same thing due to dust/sand. Take the coilover assembly out and use leverage to turn the body. Pulling the coilover out is a LOT easier than trying to work under the car. Takes a few minutes with air tools, no more than half an hour in and out with hand tools.

Cheater bars are your friends. I didn't need to use a solvent to loosen the threads, but you may need to depending on how severe it is. Remove the threaded body completely and thoroughly clean both threaded surfaces. Be sure to apply some anti-seize compound before you thread it back together to prevent it from happening again.

 

Seized coils are always the worst
