LPW differential cover. Did you have to grind?

[0mineralgrey3]

The Ford racing diff cover would have fit mine without grinding, but i have MM diff bushings and brace on mine........had to grind the hell out of that.

Yup FTBR Bushings and I am not sure if the powdercoat shifted anything. Like I said, I can only get about 5-6 sheets of paper between the letters and the bracket but so far I don't have any weird noises.

4-5 sheets of paper is not a lot of clearance. You're talking about .005" for a sheet of paper so you have .020" - .025" of clearance. But if the car is put together and you don't have any noise then it surely doesn't need to come back apart, that's for sure! :-D

Just for future reference for others with the LPW cover, this seems to be a hit and miss issue. I think it's manufacturing tolerances of the Ford bracket and the cover that makes it hit or miss.

If the LPW letters make contact with the rear support bracket, that will transfer NVH from the gearcase to the support bracket. This will in turn transfer NVH to the subframe making additional unnecessary and unwanted NVH. So watch for that if you're using an LPW cover.

Personally I would like to see a minimum of 1/16" (.062") of clearance. Preferably like .090" - .125". (1/8")

FWIW

Glad I filed my LPW logo BEFORE install. Clears by about 1/8" off the FTBR bushing kit.

thought I ground my cover plenty but it is still contacting the top welding slag of the bracket. LPW fails on this one.

When I get back home I'll check and see if I still have them in the garage. If I do I'll drop you a PM and send them your way.:beer:

Did LPW do anything different on these since this started? My LPW is on the way. What about studs for it?
