ok we have put an f20 4x4 gear cassette in the f20 2wd box. now, it whines like a bugger as if the diff bearings are shot. what i was wondering was, as the final drives are different, should we have put the diff from the 4x4 box in aswell to match the final drive cog on the cassette.? or will they be the same

cheers

yeah you should of changed the diff crown wheel. might be whining because the teeth spacing isnt quite right.

the 3.72 pinion is 18 teeth, 3.55 pinion is 20 teeth.

running an 3.55 pinion (20) with a 3.72 crown wheel (67 teeth) means you have now got 3.35 final drive and the gears smashing together !
