My Jeep 2008 Rubicon Unlimited has: 3.5Ē lift; 5.13 gears; auto trans; 35Ē tires &tc.
After 100K miles of vigorous usage my locker failed. Upon inspection, it was the connecting wires to the magnet that burned up. There are great threads in this forum that showed how to fix this and I appreciate the help given there. I tried the process listed in the other thread; but, my wires were burned into the connector so far that I couldnít get a pig tail to connect a wire to.
So, after looking at a few alternatives, I decided to replace my locker with an OEM replacement locker. That part number is 68036128AA. I found a great price at 4Wheel Parts. I got mine on sale for about $935. It was shipped directly from Chrysler. I donít work for 4Wheel Parts nor for Chrysler. The part was much more from the Dealership and I have a good dealership.
If you are going to replace your rear Rubicon locker those axles have 32 splines. If you are going to replace your front Rubicon locker those axles have 30 splines.
I looked everywhere I could think of to find just the magnet portion of the locker. I could find no details on the magnet either. I was really trying to buy just that magnet portion of the locker.
So, in an attempt to help the Jeep community, Iíve supplied some information here. Note: I am no engineer & I have only a basic caliper. The measurements are metric (inches are only close approximations). The inside diameter of the magnet is approx. 6cm. (2 3/8 inches). The width of the magnet (inside race to outside of case) is approx. 3.5cm (1 3/8 inches).
I would hope that by the time (if ever) I need another magnet to fix the rear locker on my Rubicon (100K more miles), there will be a source for the magnet alone.
There is a marker written on the magnet with the number 100412. I couldnít find that referenced anywhere in parts stores. The ring on the inside of the magnet moves about 0.4cm to engage the locker.
Here are a few pics of the magnet.
The magnet is not directly attached to the locker Ė the locker spins with the axles, where the magnet is held stationary with a ďactivator bracket.Ē Pics of the locker without magnet slid on.
When not activated, the ring on the inside of the magnet is at rest and does not press against the locker. When activated, the ring presses against the ring on the locker and the teeth are engaged inside of the locker. Pics of the locker with magnet slid on.
I hope this helps someone.
