Cool Sexy rear end

Get your attention? I have a chance to get a (sexy) Jag rear end for my T-Bucket. Anyone have any experience with them? What do I need to watch out for???
Thanks

Mrfixmaster...I'm finishing one up right now. I really like the engineering on the thing. It's all U.S. threads and fasteners (no metric), it's a Dana 44 center section, and I found it to be a pleasure to work on. One thing you might want to be aware of is the pinion is offset about 1" to the right. Your driveshaft length might be an issue. Anything specific you want to know ?

Haven't gotten far enough along to know exactly what to ask about, just wondered what problems/engineering "challenges" others had run into before I start.

Hang in there. One thing to remember is the lower arms must be level through the pivot points. This makes the pinion also level. Your engine should therefore be level in the chassis if you want good life from your U-joints.

Thumbs up

Thanks for the advice. I have bought the rear end, but it has not been delivered yet. Thought about putin it in my T-Bucket, but also thought about just starting another one!! (Haven't broached that subject with the war department yet) was really wondering about longevity. I've heard tales about the wheel bearings being the weak link of these. Any troubles there?? <img src="confused.gif" border="0">

I haven't run it yet. I sure don't see why wheel bearings would be a problem though. Especially in a lightweight T-bucket. If they stand up in a big, heavy Jaguar sedan, why would they be a concern in your application ? Check with a Jaguar dealer maybe ?

The warning I had was that they don't hold up well with really wide tires, I'm only running 12"wides, so don't know if that applies to me or not. Thanks for all your input and advice. I'll keep you posted of the progress.

A T-bucket, with about a third of the sprung weight of a Jag sedan, shouldn't be bothered by any tire size. Perhaps whoever told you this was referring to wheel offset, i.e. moving the wheel centerline further away from the upright bearing's centerline. That would create a lever effect on the hub bearings. With your light weight deal there should be no problem. I ran into my import car expert in the hardware store yesterday and he advised me to replace the bearings, etc. just inboard of the brake rotors. They are the "weak link", if there is such a thing, in the Jag rear. This is because the half-shafts also act as the upper arm in the suspension design and take a side load as well as supporting the U-joints in rotation.

Talking

About 20-25 years ago everybody was using them things over here, not much too worry about that hasn't already been covered, the narrow one was the XKE or E-Type as known over here & the widest one was the mk10, as for wear i've seen every kind on them but if you keep em greased up they are pretty good & theres no excuse they got plenty of grease nipples.
Obviously the hard one to get is the XKE but the XJ6 & XJS are common & cheap to buy over here.
good luck

Exactly ! One problem with the XKE is the knockoff hubs. My '91 XJS uses Chevy wheels. It's going into a street-legal 60's sprint car and I've narrowed it from 61 1/2" over the wheel flanges to 50". It measures 25" from each wheel flange to the pinion centerline.

I paid $250.00 for it on eBay.

A lot of the Jag rears are posi....mine isn't. I haven't researched gear ratios much but there are many different ones available. Mine is a 2.88 : 1 and, with my 33" rear tires, at 7000 rpm in drive I'll be going 238 mph....
