[QUOTE="Bad Company, post: 15913135, member: 141815"] You've driven the car enough miles with the 3.73 gears that you'll never get them to be quiet. The reason for this is you've already put a wear pattern in the surfaces of the ring and pinion gear. To change the pre-load and backlask with the correct shims is to change the position of the two gears in relationship to each other. This means the wear pattern you've already established wont be in the exact same position of the gears. It will be noisy no matter what you do from this time forward. As for the tools required I found a used Ford Rotunda ring and pinion install tool kit on Ebay for the 7.5" and 9" rear axle assemblies. This kit has quite a few of the same tools required for the 8.8, the few it didn't have I was able to buy individually to have the complete tools required to build the 8.8. Ford has discontinued making these tool kits or selling the parts individually. OTC was making these tool kits for Ford and selling them under the Ford Rotunda name. OTC sells the tools individually, unfortunately this is an expensive way to purchase these tools now if you are looking to buy them new. Here is a link to a Ford Racing Installation Instruction PDF for the 8.8 gears. On page 8 there is a complete list of the tools required to set the pinion depth correctly. I Googled these tool part numbers to find the tools for sale used. I was lucky to find an old complete Ford Rotunda tool kit for the 7.5" and 9" rears on Ebay with most of these tools. Looking at it I doubt it had been used more than a few times. The few tools it was missing to do the 8.8 I was able to purchase on Ebay or new from OTC to be able to do my 8.8 rear.
