Re: radius control arms on the rear? (TJ)
He He -- with the tires rubbing on the coil pads it's not going far! I was thinking of the freeway ride home! Good justifaction for an on-board welder!
The Terra short arm does it too? The arms still use the original stock mounting points, one above the other, don't they?
Maybe the "side by side" of the Fab Tech isn't the cause after all.
Yes for sure -- the "kits" usually use a longer Trac Bar mount on the axle end - it bolts on to the stock mount. That increases the stress on the stock mount's welds, they break! It's not really difficult to re-inforce that mount with gussets.
The frame end also needs re-inforcement. In fact, it helps with windsteer and bumpsteer to extend (lower) the mounting point of the frame end too. (Actually that trac bar should be parallel with the ground to get the least "steer," not practicle though.) For sure then it needs re-inforcing gussets! I also re-inforce the frame at that point to distribute the load. Wish I took pics of the ones I've done. I haven't done mine yet -- yet!
In fact, it couldn't hurt to gusset ALL the mounting points on the axle. They are flimsey.
And, you need skid protection on the lower bar mounts -- the U-bolt style protectors are junk - they bend and break the U-bolts, and don't do anything to strengthen the mounts.
I saw one front that was bent way over to the side -- and it had the U-bolt skid plate still on it!
