First post so Hi everyone,

I eventually got started with this project and will need some help and advice.

My first issue is with the Ford 9" diff pinion support and bearings preload. The original pinion support was damaged and I got a Daytona type aluminium support from Summit. Got the proper bearings (the head bearing is larger than the stock one), assembled the pinion system with a crush sleeve and paused to observe. The Daytona pinion support is about 0.3" taller than stock (from case mounting flange to seal surface) and this explains why the pinion shaft threads are still recessed inside the nut when the spec bearing preload is attained (16 to 29 in lb). Another worry is that the preload spec values are reached very early without crushing the sleeve at all. The yoke is the stock 5" tall model. Obviously there's something amiss here. What do I do? Shorter yoke (which one)? Set preload with solid collar and shims as opposed to a crush sleeve?

Any advice will be appreciated,

Marc.
