What kind of differential does a Jaguar XJ use?

What kind of differential does a Jaguar XJ use?

All XJ-S differentials are limited slip, and all the systems operate using essentially the same principle (a series of friction discs, with the compressive load increasing through increased drive torque) although the feature has often been given different names. The gears for the DANA Type 44 limited slip differential will fit in the Jaguar unit.

How long does it take for a Jaguar differential to fail?

Probably the most common major component problem with Jaguar automobiles is carrier or output bearing failure in the differential or rear axle unit. Jaguar diffs will usually develop the characteristic whine of a damaged and failing bearing by at least 100,000 miles, in some cases sooner, but in almost every case by 125-130,000 miles.

What kind of suspension does a Jaguar XJ6 have?

The rear suspension is an independent type suspension which also have coil spring/shock absorber assemblies and a lower control arm. The rear driveshaft acts as the upper control arm. Power-assisted Anti-lock Brake Systems (ABS) with four-wheel disc brakes are standard equipment on all Jaguar XJ6 models covered in this manual.

What kind of wheel carrier does a Jaguar XJS use?

In later XJS models with outboard rear brakes, the wheel carrier, brake discs and parking brake drum were a single cast steel unit. In all cases the wheel carrier runs in bearings mounted in a large cast aluminium hub carrier. Each lower link is fabricated from a steel tube with a two-pronged fork welded to each end.

What’s the differential on a Jaguar XJ6 / 12?

Good information, but am curious about the 3.07 listed for Series III XJ6/12. My 85 Jaguar Sovereign European version is stamped 3.058 on the differential tag. Did you round this up to 3.07?

What kind of transmission does a Jaguar XJ6 have?

Jaguar XJ6 Service and Repair Manual 3261 Jaguar XJ6 Models covered Jaguar XJ6 models with 3.2 litre (3239 cc), 3.6 litre (3590 cc) & 4.0 litre (3980 cc) six-cylinder in-line dohc petrol engines and automatic transmission

How long does a Jaguar rear differential last?

The differential in your Jaguar is very robust and long lasting. Providing that it doesn’t run low on lubricant expect a life of 100,000 miles with no problem. Many owners nearly double that figure before an overhaul being needed. To check the oil, you need to elevate the car.

How are side bearings adjusted on a Jaguar differential?

A nice convenience is having an extra pair of side bearings that have the centers honed so they slide on and off the carrier easily allowing you to press on the new bearings only for final assembly. Pinion depth is adjusted by adding or removing shims from behind the inner pinion race.

How often should I drain my Jaguar XJS differential?

The differential has a combined filler/level plug and a separate drain plug. The oil should be up to the base of the threads in the unit. Every 20,000 miles (approximately), drain the final drive unit (after a run, when the oil is warm and flows more easily) and re-fill with fresh lubricant.

What should I do if my rear differential goes bad?

The rear differential cover is typically silicone or rubber and can deteriorate and leak. It’s the easiest to repair – all that’s required is removing the rear differential cover, cleaning the sealing surface, and resealing the cover. It’s all done in less than an hour.

What should I replace in my Jaguar XJS?

Frequently, these repairs are replacements with the AC compressor, Air filter, Brake components. Crankshaft balancer and door actuator among many others being the most frequently made replacements in auto shops. By many criteria, the XJS series models are considered collectibles, young classics if you will.

How often does a Jaguar rear differential need to be drained?

The Jaguar service manual specifies that the oil be drained and the unit refilled with fresh oil every 30,000 miles (4800KM). There is a drain plug at the bottom of the differential for this purpose.

When to replace rear rotors on a Jaguar XJ6?

And if you have an inboard brake Jaguar, such as an XJ6 Series 1, 2, or 3 sedan or an XJ-S, be sure to replace the rear rotors at the same time as the differential; either procedure requires dropping the rear suspension assembly from the car. This is not a job you want to have to do twice!

What kind of oil does the Jaguar XJ final drive use?

Note that while the diff can be topped up with conventional gear oil, a drain and refill requires an additive for limited-slip units. According to a salesman at Quality Jaguar, the XJ-S final drive unit uses both natural leather and natural rubber seals.

A nice convenience is having an extra pair of side bearings that have the centers honed so they slide on and off the carrier easily allowing you to press on the new bearings only for final assembly. Pinion depth is adjusted by adding or removing shims from behind the inner pinion race.

How to check the transmission on a Jaguar XJ?

Check the connector on the transmission (driver’s side) if it has the rubber boot, or check for the connector’s connection cleanliness, check pins if they are not corroded, use electronic parts cleaner. Check for trans mount, if it’s gone the trans will move more then it was designed and can cause connection problems.

When to change differential lubricant in Jaguar XJ?

There should be no significant movement of the wheel.) Second, Jaguar does not list a differential lubricant change as part of the scheduled maintenance, as most other manufacturers do, usually at 30,000 mile intervals. Our experience is that changing the diff lube will delay the inevitable failure of the diff output bearings.

What causes a Jaguar XJ transmission to neutralize?

Neutralization of the transmission (car running, NO engagement of the transmission until it slowed to 30mph) was due to a bad ABS wire, and misalignment so some sort of the left rear ABS element at the wheel itself (or so I’m told by the mechanic who fixed that issue).
