I got the following message today at KOR from a customer looking for more information about WJ Steering Stops today:

“Hello, I have placed larger tires on a lifted wj and I am having rubbing issues on the control arms at full turn.  I read one of your post to weld washers to the knuckle.  Could you please explain to me where do I weld the washers exactly. Or maybe a photo.  Your post has help me very much.

Thank you”

So, thought I would post a follow up to that same forum post with more information so that others know exactly what I’m referring to.

If you poke your head under a ZJ, you’ll see on the leading edge of the Dana 30 front axle (the front face) at the outer edges a slightly raised area that is turned maybe 45-degrees outboard (toward the tires) and in the shape of a small square.  This is the “landing pad” for the head of the 10mm bolt you’ll see which is threaded into the bottom front of the knuckle on the inboard side (both left and right).  These bolts can be loosened (turned out) and will contact the square landing pad sooner, stopping the tires from turning as tightly, and as such, keeping larger tires rubbing on the control arms.

The WJ’s Dana 30 axle never came with this bolt.  My suggestion is to grab some steel washers that are thicker than normal, and “rosette weld” the washer to the leading edge of the D30 axle in the same spot the ZJ “landing pad” is formed, to keep the knuckle from turning so tightly.  A “rosette weld” is, essentially, filling a hole of a new piece of metal with molten welding wire, soo that it “pools” in the hole, thereby bonding it to the existing piece of metal.  Search Google Images for “rosette weld” if you’d like a photo.

The more washers you stack and weld, the less the steering wheel will turn, and the less the tires will rub on the control arms.

Bear in mind this does reduce your turning radius slightly more than driving with the tires rubbing, as the rubber is malleable, and “slips by” the control arm…allowing the two things to exist in the same plane while you have the steering wheel cranked tightly, whereas after the washers are welded on, the tire will never go that far again (unless the washers are removed) and as such the turning radius will not be as tight.

A small price to pay, in my opinion.

I hope this helped, and Happy New Year to all the Jeepers out there!

Most Sincerely,
Kevin Fell
