I have a 2001 250 SD that I would like to lift 2" in the rear with either a 4" non-tapered block or an add-a-leaf. My truck has a two piece driveshaft. I have been told three things regarding potential driveshaft angle problems: 1)use a driveshaft shim kit, 2) have the axle tilted to compensate, 3)do nothing, it's not enough of a change to matter. Any help would be appreciated.

 

Shim the carrier bearing.

 

Going up 2" in the rear probably won't require much of a shim. Probably 1/4" up to a 1/2" shim at the most. If you're on an incline, park your truck facing downhill and chuck the wheels. Should be less than 10 minute install.

 

Thanks for the help DC Special and Pocket.
