Troubleshooting - Drive Train

Applies To:

Range Rover Classic | '87 - '95

We had a vehicle with an interesting problem. When in park, the vehicle would slowly roll down an incline. Initially, it appeared to be a problem with the transmission but upon further investigation, it turned out to be a bad front CV joint.

The problem would look the same as if the vehicle has a broken rear axle. Because the Range Rover has a full time four-wheel drive, the problem is not as obvious as one might expect. The underlying problem was a lack of 90 wt. lubricant in the swivel ball. The front differential is often serviced, but the oil in the swivel ball also needs to be checked separately. There is an inner oil seal which prevents the oil front the differential/axle casing from moving into the outer portion or swivel ball on the front axle. Because the swivel ball seals can leak, it is critical that the swivel ball seals be checked. We recommend at least twice per year. This simple maintenance check can save you big dollars in repairs.
