4ha axle

Hi, Just wondering if a 4ha axle off a mk2 jaguar will fit under a unarched chevette?

Thank, Rob

Yes, IIRC, it's the recommended one - IIRD, it's a half inch per side wider.!
Also raises the question - if the solid axle fits - will the independent version from the Mk2 S be a viable conversion!
I was hunting one of these up 20 years or so ago as I figured it'd be perfect - huge range of ratios 2>88 to 6.3 (rather less now, though), VERY strong, inboard disc brakes with handbrake with aftermarket upgrades available if needed, reduction in unsprung mass and what additional mass is there is low down and there are several types of LSDs available to suit what one needs.
Many of those points still apply to the standard Mk2 diff'.

The main drawback, apart from the weight, is the bolt pattern - 4 3/4", 5 stud but as that's quite common - also used on the American Chev's and BMW (I think), for example, so wheels should be easy to source. It may be an idea to have some alloy front hubs machined up to the matching pattern and while doing it, the wheel mounting face can be positioned for the best clearance to the damper and the inner flange for the disc you intend using. Otherwise you could have the flange redilled.

It's 1415mm accros the hub faces, which seems to be 15mm wider than the manta a axle.
Will that be ok under the standard arches?
Thanks, Rob

It should be ok, that's why i got one, but you may want to roll the arch to be on the safe side.

Thanks for the replies.
The pinion flange is offset on the axle, around 2 inches to the right from the centre I think. Will this cause any problems?

May do, dummy up the diff with it resting against the bump stops and grap a bit of exhaust tubing to represent the driveshaft, it'll give you an idea if the tranny tunnel needs a little 'reworking'.
