LSD on XJ Limited? Plus other questions...
 

Can anyone confirm whether the 94-97 XJ Cherokee Limited's were fitted with
a rear LSD as standard? I'm specifically talking RHD 4.0ltr Aussie models.
I know that the Sport models had the rear LSD, but I've been given mixed
info on the Ltd. Is there any was to tell via tags or part/serial numbers
on the rear axle?

I test drove one yesterday with 230k kms which has had a hard life (lots of
towing) and if it had an LSD it appeared to be no longer functional. I
didn't jack it up to check, but could find no evidence either way by just
looking at it from under the vehicle. Really bad driveshaft wind-up and
heaps of driveline backlash (not helped by an off-idle stumble). Also any
thoughts on the engine stumble? The trip computer only showed compass and
temp, if the left button was pressed to show fuel usage, etc the display
just went blank - is that normal or indicative of a problem?

Any experience/info/help would be appreciated.

Cheers, Clax.

No, the LSD was not standard. It was strictly an optional extra-cost
upgrade. That stumble wasn't caused by you trying to drive in 4wd on a
paved road was it??? The Commandtrac 4x4 system can only be used offroad.
Driving in 4wd on a paved road will cause bucking and jerking due to the
drivetrain being locked up and binding on the pavement.

Re: LSD on XJ Limited? Plus other questions...
 

No I wasn't in 4WD at the time. :-)
I'm a driveline engineer, so I'm well aware of the issues that would cause
(wind-up, bang, crunch, walk-home, followed by a nasty surprise at the
repair bill). This was definitely engine related, it would also do it in
neutral and park while stationary.

Jeez I hope the Aussie Ltd's got the LSD standard, or I'll need to re-think
getting one. I might need to slum it in a Sport instead... I've got a
factory video for the local '94 model Ltd, and in that they state that all
Aussie Cherokee's got a rear LSD - "Trak-lok" they called it. I wonder if
they deleted that with the 95 upgrade?

I don't suppose there's any way to cram a Dana 44 centre into the rear of an
XJ? What do they run, a 32? I can get lockers for a Dana 44 no worries
(they're used on a local Ute (pick-up) variant). Mmmmm, I might need to
take a look at that local '84 with the 360 in it...

Any ideas on ID'ing whether it's an LSD or not visually?

Cheers, Clax.
