Problems With Freelander 2
This biggest issue with Freelander 2 models is definitely the transmission.
The key problems with the drive train can be resolved and should be the first thing checked when purchasing a second-hand Freelander 2.
Problems can start from the new style 4WD system that Land Rover used on all of the Freelander 2 models apart from the 2WD 2.2 diesel eD4 model.
The rear differential now has an electronic coupling system, which is called the haldex unit. If this part is not serviced on time it will cause significant issues that will end up causing damage along the drive train.
The haldex needs to have the oil and filter in the unit changed every 60,000km. If this does not adhere to the haldex starts to block up which will result in the car running in 4-wheel drive all of the time which is not how the vehicle was designed to function.
Apart from making sure that the haldex unit is in tippy-top condition the rear differential itself also needs to be maintained. The diff has a particularly weak nose pinion bearing (the smaller of the two pinon bearings). This in turn puts stress on all of the other bearings in the unit, so the complete differential will need to have all of the bearings replaced at some point in time if you want peace of mind.
There is also the front transfer box which has an intermediate shaft that connects from the transfer box to the gearbox via a splined sleeve. This is not lubricated at all and water easily reaches this area which rusts the splines and in time the parts fail. The transfer box also has a week pinion nose bearing which as with the rear differential causes damage to the rest of the bearings. This means that all of the bearings will need to be replaced in the transfer box to resolve the problem.
Once all of these areas have been checked and resolved you will enjoy many years of headache free transmission.
