HELP i think i cross threaded subframe mounts
 
I'm about to cry. I was hand tightening the bolts that hold the rear subframe after installing the rear whiteline bushings n it just stopped. I can't turn it at all after about a half inch. I took the bolt out and there's metal shavings on it. Omg what do I do

The car is destroyed. Might as well sell it

probably stripped it, if you don't have the tools for repair, take it to a shop

You can try a long tap so you don't have to remove anything.

I actually bought one of below to clean up a tread, mind you this tap took a few weeks to come in:

Hope that helps.

the problem is not even that you stripped it

its why you stripped it

the answer to which is that when you were re-installing it, there was uneven torsion on the frame.. or similar and the subframe wasn't perfectly aligned with the chassis

this is a real pain in the ass. Not a problem under shop conditions where the frame is evenly supported, but if you were doing this on jackstands, there is a good chance you had it mis-aligned as you were torqueing it down.

thanks, I'm going to try to get a tap now. I don't think local parts store will have this size. I'm gonna have to bring it to a shop to get them to fix it I think.

car is on jack stands, that probably why it happend. Only back is up which is messing everything up

Exactly as what 7thgear have said.

Once you have the bolts undone, the subframe "misaligns" slightly. I had to use jacks to bring up the subframe / loosen the other bolts to align it.

Make sure you just use your fingers to get the bolts in and have at least a few turns before using a ratchet. You could look into the hole to see if it is align or not, but more importantly, go by feel and that is using your hands to get threads started. If it doesn't go in, stop and try to realign.

Good luck and hope you get your car fixed soon.

thanks for the info guys. Cars at a shop now, the mechanic said its actually not that big of a deal, and that he fixed those threads before. I got my fingers crossed that I get my car back quickly with no complications.

autoCAR 10-23-2013 06:31 PM

just an update, cars fixed n I'm driving it. Mechanic said I'm lucky, 2\3rds of the threads were still good. He removed the whole subframe retapped the sheeread threads, reinstalled everything w the bushings, and he said "do yourself a favor, don't ever take these bolts out again"

NemeGuero 10-23-2013 06:45 PM

what'd he charge you for all that? just curious

RallySport Direct 10-24-2013 12:13 PM

Every time I do the rear subframe bushings I have to be super careful putting the bolts back in, and always double check the alignment of the subframe. For some reason these particular bolts seem to want to cross thread more than any other bolt on the car haha. Glad you got it fixed, and this is the exact reason I have plenty of taps and thread chasers whenever I work on something lol.

This should be a good warning to anyone doing these bushings. Just be very careful putting those bolts back in :)

Thanks,
Rick

he is a friend of the family, and he saw I was genuinely upset about the whole thing, so he didn't charge me. I tried leaving him 100 bucks but he didn't take it
