Thought I would post this up for everyone so that you can consider this when looking to rebuild your Ross box. I rebuilt mine a couple of months ago with the following parts: -new seals/bushings/gaskets -new sector shaft -new bearings -tightsteer installed -new pitman arm I did re-use the original worm drive as it showed minimal signs of wear. Shortcut to today, the Jeep has driven 523 miles since the rebuild and the steering has been getting progressively looser. At first I thought it was a break-in of the new parts, then I made some adjustments to the tightsteer. Today I opened up the box: finding a glittery chips in the gear oil and this: The Omix-Ada part with 523 miles on it is on the left, a factory Willys sector shaft with 50,000 miles on it is on the right. Obviously this part was made from completely sub-par cheap steel. I will say that the tightsteer setup is likely the only reason I was able to drive without the steering binding. Needless to say, this cheap part gouged the worm gear and ruined it. This is the kit that I used: http://www.kaiserwillys.com/product/825/willys-jeep-steering-gear-box-repair-parts-accessories I am not saying anything bad about Kaiser Willys at all as they have been great thus far. I'll be contacting them to get a refund for this part, I'll let you guys know how they handle it. Stay away from this part!!! Find a ross box at a salvage yard and re-use the factory internals!
