Outer Limits 4x4 Board

G'day,
My '91 cruiser has about 3 inches of lift and is running 315/75/16s. I have a set of urethane 2 degree castor bushes but haven't fitted them yet. I'm worried about the chance of cracking the diff housing with these stiffer than OEM bushes.
It drives pretty good so I haven't been too bothered but since they are sitting there I would like to see if there's much improvement after fixing the castor.
Have many here fitted these type bushes and had/not had this problem?
cheers,

i have a three inch lift and i have fitted poly 3 deegree bushes and have not had a problem with them.

i should of went four inches of lift is my only problem

Gday
Ive used bushes before and while the fix the caster, they bind up articulation...and if you wheel alot, will crack the housing. A real easy way to do exactly what the 2 deg bushes would do is to take one arm off at a time and elongate the front hole 14mm, and align, then put washers on each front bolt and tack in place once in position...
