My first post here so hoping for some advice,
I have a 1999 3.4 manual with a 4.1 diff. The car has served me well having survived a rollover and many other off road adventures. Of late the rear diff started to make terrible noises and fearing a seize up I disconnected the rear tailshaft and now drive front wheel drive only - its a pain as no LSD so she slips easily on wet ground. Turning the input pinion for the rear diff feels like a bucket of gravel.
So I searched out a diff on Gumtree. (beware their are liars out there) A full rear end was on offer supposedly for my model (2002 3.4 RV manual). I went to pick it up and could not turn the pinion due to the brakes being seized up. I was doubtful, but the seller was adamant it was from a 2002 3.4 litre car as indicated.
Got it home and on stripping found that it was from a 2003/09 4 litre with a ratio of 3.7:1, not 4.1:1 as mine is. In fact the whole assembly is wider as the 120 series has a different track - axles are 30mm longer. But I thought if I could use the diff and disconnect the front drive shaft I would have a usable car in RWD - better than FWD as rear has a limited slip diff, it would still be quite capable off road.
So I pulled out the old diff and fitted the replacement. All seemed good until I found that the tailshaft yoke on the 120 series has 65mm hole spaces as opposed to 60mm on the 90 series.
So the question is, will the splined yoke from a 120 series tailshaft fit my tailshaft? If any one has a yoke they can measure I would be grateful. I need the spline diameter and number of splines.
