trickydicky Posted July 2, 2010 Share Posted July 2, 2010 hi can anybody tell me if there is a diferance between a front and rear diff if there is can you tell me what it is . if you put a rear diff on front then wont the pinion gear run in a diferant direction ? surely that will make it wine ? thanks richard Quote Link to comment Share on other sites More sharing options...
Off Road Toad Posted July 2, 2010 Share Posted July 2, 2010 Front and rear diffs in Land Rovers are the same in standard form. and yes that means the front diff is rotating the wrong way. they don't (shouldn't) whine. It does mean however that the front crown wheel and pinion are weaker as it is running on the coast side of the teeth. Also it doesn't oil the pinion tail bearing so well. you can get round this by fitting an aftermarket ring and pinion with 'reverse cut' such as those we make (or others).

Bush65 Posted July 2, 2010 Share Posted July 2, 2010 Just to add a little more ... Beware of putting a used rear diff in the front or vice versa. They could have experienced many high load cycles applied to one side of the teeth and now would be loaded on the opposite side. This can lead to reduced fatigue life before failure. I'm not saying don't do it to get out of trouble, but avoid swapping them if it can be avoided. Quote Link to comment Share on other sites More sharing options...

However, if you can choose, then be aware of this issue, unless also intending to fit new gears. Quote Link to comment Share on other sites More sharing options...
