Gearbox Backlash - anyone tinkered?

[hoolio]

Has anyone altered any out of limits backlash in either a rear diff, Gearbox transfer case or 'ring gear & pinion' etc? Done by adding or subtracting pinion shimming?
Im curious to know, Not such a straight forward exercise in a four wheel drive I would imagine??

If the backlash was corrected in the transfer case by 'mucking' with shimming is it possible that simply you have now altered when the loading takes effect ?
ie the Rear wheels may in fact now carry far more drive loading than the Front wheels - in a four wheel drive application - because you have only adjusted one of the ring gear & pinion setups?
ie before the setup had been touched everything could be assumed to have worn equally therefore the loading on front & rear drivetrain could be assumed to be uniform...?

Confused? - great me too.
Input any one?

Never rebuilt a diff myself, but when watching and talking to my dad he said that backlash isn't all that important. As long as the contact patch is in the right place and the right shape it can't be wrong.

Don't have a clue about the 4wd stuff though.

dont think it will effect your fwd/rear bias at all.

has no relation to bias at all

Mmm ok, I'll Rip Sh%t & Bust & see if I cant remove some of the play in the prop shaft.
Thanks.
