Greg,
I understand your predicament buddy! I gota 2003 V6 'Luxy and me rear diff went at 30,000kays. It's a manual, got 2"lifted
suspension and at the time I had
Dunlop MT1 31" muddy's on it. Happend on the monday morning drivin to work after a weekend of 4x4'ing, when I gassed it slightly over a speedhump at the servo, the rear wheels jumped up over the bump but as they landed an almighty bang! Took it to a dealer coz they wouldnt let me do it at the workshop I work in, and they told me straight-out that it wouldn't be covered under warranty because of the
suspension and tyres contributing to my problem (they reckon). There was another hilux in at the same time with the front one blown after 4x4'ing too.
I told the service manager he can stick his warranty up his rectumm, and I was gonna take it
home and slap in a 2nd hand one for $750, for the complete diff. (new one I was quoted as $2,600 - bugger that, put in a nine inch for that money). I talked to a few blokes I new within Technical
Services at Toyota and got meself and the other poor bugger covered under warranty.
I've had 2more V6 hilux's with rear diff at my workshop, me mates neighbour blew his after 3,000kays, and a bloke at
melbourne city toyota reckons they've hada few too.
It comes down too a couple of things, the IFS hilux's have a 7.5" diff centre as opposed to the live axle hilux's which had 8" diffs, supposedly much more stronger. This 7.5" diff was okay for the low torgue 2.7 petrol, and the 3.0 dieslels, because of the relatively progressive way they slowly apply power, but when they slapped in the V6, the larger instantaneous torque you get when you put your foot down is too much for the 7.5" diffs. add to that the stress of larger tyres etc and they go......
The front diff can't be hammered hard in reverse in four-wheel drive low (i.e. reverse snatching someone) because of the way the gears are cut or something.
Mine blew at 30,000kays and I got 74,000kays with 265/75x16 so it's holding up okay so far. sorry for waffling on, hope it helped!!!
