rear frame repair

here we go! I bought a 1990 yj yesterday and the first order of business is repairing the rear frame where the spring shackles bolt on. I saw the 3 piece kits on ebay with 1/8" steel for about $66 for the pair. I think this is the kit for me but looking for input from people that have been down this road already. looking forward to a fun project!!

I also used the safe T cap. Very straight forward and made it somewhat easy to fix.

Did you have any problem fully welding the inside rail? My 98 TJ is in the shop now and my welder is telling me that he can't fully weld the back side without lifting the body off the frame.

I did the saf-T-cap rear frame repair as well (94 yj).
Welding the inside rails was a pain but do-able.
Removing the body will make it easier but it's not 100% necessary.

If I had to do it over, I'd probably trim the repair sleeves down 1/2" on the inside to give better welding angles (if there was enough good factory steel there to weld to).

Obviously the gas tank has to come out to get in there.
Then it's just a matter of welding in a very uncomfortable position.
I hope your guy is using a MIG, if he's trying to stick weld then yeah he'll never get a good angle.

good info!. ive been talking it over with some friends this weekend and even though they are almost 300 for the pair as opposed to welding the 3 plate kits on which are around 66 a pair, we think the safe t caps are going to do a lot better of a job and will be stronger.and I like that they come with the tube installed to mount the shackles. I think I am going to order them tonight.

Wise decision, the po did plates on mine and it looks like crap. I do realize the expertise of the welder makes all the difference, something this guy did not have

You will like the safety caps easy to install and fairly straight forward. Check the rear cross members that the tank bolts too..mine were shot along with the frame. Ended up repacing both end sections of the frame and the cross members and added shock towers.

had the problem, however since i had no garage, neither the welding skills, i had to pay metal shop to do it. Cost 150$ per side, including metal, labor, cleaning and etc. NYC area.

To be honest it was quiet fair. I looked through most kits, and best i could safe if did it my self would be 70$ total. which did not made sense, considering i could mess up on welding too.

I can weld but I'm not the best. I ended up buying the cap from Quadratech and with a buddy of mine we welded it in. It took a Saturday afternoon and was pretty easy. We didn't have to raise the body off the frame but we did drop the gas tank for safety's sake.
