On the passenger side where the spring pad is there is the two bolt holes for the u bolt plate ..mine are stripped out from the guy that did y cage way back on the 4 runner. Well it looks like he just ran a bigger bolt down in the holes. After changing out springs today the bolts have ruined the threads. So can i drill and tap for a larger size bolt....he ran a 5/8 bolt in them . Reason i ask is my next option is a 3/4 hole and im not sure on the type aof material the third is made of and how much material i have to tap.

If it were mine I would heli coil it.
I thought about that but wasnt sure about the strenght. If you think its fine ill go that route.

Strength shouldn't be a issue, I've done several of these this way. Usually the threads get rusted out because water collects in there.
Ok...done deal Thanks .:awesomework:

Most of the time the Helicoil is stronger than what was originally there.

Screw it Brian, just link that SOB!!!!:haha:
Im debating it. I just dont want to throw the coin into it right now. Just want to beat on it for awhile.It got beat on sunday if you couldnt tell.:redneck:

Yeah, I noticed....:awesomework: Kinda nice bein' out again, huh!!!:awesomework:
Yes and no. Running the import **** I never really had to worry about breaking stuff. Now having a v8 im really scared of breaking. Like when the power steering pump broke.....

GM pumps are known for breakin the shaft...replaced many over the yrs...nothing new, or likely that you did. Just happened would be my guess..

heli coil and put studs in it so when your wrenching down your not trashing on the threads and housing.

Like kevin--see that alot. But it was like 96' and newer...

That would be my fix......

heli coils are stronger than normal threads in mild steel, cast is even weeker.
Heli coil them put studs and be done with it.
(heli coils are approximately 30% stronger than normal threads in mild steel)

One thing to remember about helicoils--they truely are only as stong as the surface they are set into....

USE STUDS NOT BOLTS As stud can be bottemed out and use ALL the threads available. A bolt will leave unused threads below it.
Any one ever put studs in then heated it up enough to draw some brass/braze into the threads?
Kinda like soldering a nut on a bolt on hobby **** to keep it from backing off.

not necesarily.
the reason they are stronger is because the distribute the load better.
I am looking for the tech write up on it for exact numbers.
on a normal tapped whole, 90% of hte load is on the top 2-3 threads, as where with the heli coil, they are more evenly distributed throughout the tapped whole.
for example, rule of thumb for bolt installation is to have it threaded 1.5 x Thread diameter (there is a formula for the calculation, but it always falls inbetween 1.4 -1.6)
With a properly installed heli coil you can take this down to 1:1 because of the load distribution.

I found AN article.. but not hte one i was looing for.
