Okay, I need to order new U-Bolts today, and my XJ is 30 miles away.

I know they need to be 10" long aprox, but I didn't check what the diameter of the bolt itself is, or the diameter of the tube.

Anybody know these off hand? Or have one they can measure up? It's a D44.

Thanks

Okay, thanks Chuck.

Edit: Nevermind, I was off.

Any ideas on bolt diameter? Seems like it was bigger than 3/8".

As usual, I'm too late.

They are NOT the same for the Dana 35 and the Dana 44.

Dana 35 u-bolts are 2-5/8" inside clear width (3-1/8" center-to-center) and 5-1/2" from the inside of the loop to the end of the threads.

Dana 44 u-bolts are 3-1/8" inside clear width (3-5/8" center-to-center) and 6" from the inside of the loop to the end of the threads.

Both are 1/2x20 thread.

These dimensions were just measured from OEM parts. The Dana 44 u-bolts are NEW factory parts still in the bag with the parts tag on it.

I got the demnsions from a package of new Trailmaster bolts #40005.
These bolts were to be used to replace the factory bolts on the 87 with the Dana 44 when it was pulled and a D35 was put in its place.
The factory bolts were in such good shape that they were reused on the 35 housing.
The new Trailmaster U-bolts and the used factory bolts are a snug fit around both the 35 and 44 housings.
Both fit in the factory top plates(stock 87) and there is no room for a wider spaced U-bolt.
These U-bolts would not work on the 8.25 as they are too narrow,that is where the 3 1/8 U-bolts work.

The info I gave the U-Bolt shop was the length I needed them (10"), the diameter of the bolt itself (7/16") and the dia of the axle housing (2-3/4" -0" +1/8" deviation tol). So from there, they'll build them the way they should be built, so I should be good to go. Thanks guys.
