hey guys. an unfortunately event occurred. i have stripped a subframe nut. the one that holds the LCA bolt. is there any way i can fix this or is there an alternative to solving this issue?

i have thought of:

1. drill out old subframe and weld on a new one (problem: need to find the part and a place that will do it)
2. use JB weld and thread tap it. ( problem: issues with strength?)
3. drill out the nut, and get a longer bolt with another nut on top of the old one (problem: issues with strenth, and clearance)

i would like to hear all of your suggestions and recommendations. thanks everyone!

 

so what exactly broke, the lca bolt?

 

im interested to know too

 

can you tap the old nut to a bigger size? (use lots of anit-seize). also i know there is something, i think its called heli-coil. they use it on stripped out head bolts or studs. that may be an option. maybe someone else can chime in to correct me or confirm this method

this is out of the question because if i use a bigger nut, i will have to use a bigger bolt. and a bigger bolt will not fit into the hole on the LCA. thanks for the input tho.

there's a welded-on nut on the backside of the subframe. that nut is stripped. not the LCA bolt.

aww thats tru i didnt think about that. well maybe if you get a bolt that has a more coarse thread pitch. but the same diameter. you may be able to tap it like that

good luck

 

i have just contacted a shop and then said that they will do it for 1200 including parts. they do not install customer parts. sucks! 1200 is not even worth it to me. the car is probably worth only 6000 at most.

LMAO thats rape right there. Buy a drill, drill the threads out, buy a longer bolt from Kragen and put your own nut on there. It will be fine. Thats what I did, except the welded on nut actually broke off my subframe.

Total cost is probobly under 5 bucks for the bolt and nut. drilling threads is easy work.


Another idea is just to knock off the welded nut with a hammer and chisel, and use a factory bolt with a matching nut on the end.

tell me about it lol. i have drilled out the original nut and put a longer bolt in. everything looks good and i used another lock nut behind the original with a lock washer.

M10X120mm 1.25 pitch @ nutty.com = 2.10
8 3/8 or M10 washer @ OSH = .65
M10 lock washer @ OSH = .10
M10 1.25 pitch nylon nut @ auto parts store = .99
TOTAL = ~4.00

 

Is this the bolt that holds the LCA to the chassis?
