So I got a 91 yj renegade for 1400 last summer. Live in Iowa so knew rust would be a problem. No floors so since I work in an aluminum plant I got some plate and fixed those up. Now to the real fun, I am planning on doing a small 2 to 3 inch lift by swapping leaf springs and shocks. But my rear frame is rusted through where the back shackles hook up to leaf spring. Do those repair patch/plates that I can order from quadratec work good? They are $100 + each or should I just weld in some steel plates and call it a day. Rest of frame looks good but not driving it now and will be putting it under the knife real soon so I can begin the lift process.
Im not familiar with the patches ur describing. I personally make my own patches either out of 1/8" plate or angle. Cut out all the rust & attach the "home made" patch. By home made i mean fabricated. With enuf time & effort, the repair could look factory again. Hope this helps !
I just had my rear frame repaired on my 91 Renegade in January. I bought the shackle area pieces from AutoRust.com It's called "Safe T Cap". They were fabricated nicely. Steel was .117" thick and pre welded nicely. I had the local weld shop drop the gas tank and weld them on for $300.
I bought the SAFE T CAPS for both sides if my rear frame and had it welded to repair some serious rust. A long as the top 1/4 or so of the frame is solid enough to weld to they are a good fix. Just mark where your original shackle holes are.
