FWD cars dont have a rear axle, the wheels are mounted independently, there may be some situations where there is a tube there, but it will not have an axle shaft.

What you are describing is a normal condition. The drive axle is connected to the Drive Pinion Gear which is meshed with both Differential pinion gears. As you turn the wheel both of the differential pinion gears rotate around the other drive pinion gear since it's being held by the other wheel on the ground. This turns the Carrier which is attached to the ...

Yes, gear ratios are the second largest influence on your fuel consumption. Number one being maladjusted timing. I always relay the story of my and my wife's cars: she has a 1.4 Opel Corsa and I have a 2.0 Turbo Coupe. While my car has more than twice the power of hers and weighs 350kg more, we get about the same consumption figures (she gets 12.5km/l and I ...

Your truck is most likely equipped with an open differential. This is a normal condition. A few vehicles are equipped with what is called Posi-Traction, Sure-grip or locking differential. These differentials are equipped with internal clutches that spin both rear tires when moving in a straight line. When going around a turn the clutches release allowing the ...

The wheels just ride independently on bearings, they aren't connected by an axle like in a RWD vehicle. I think you misunderstand the true purpose of a differential. A ring and pinion is necessary to take the rotation of the driveshaft and change it's rotational axis. That is, the driveshaft is spinning about an axis from front to back of the vehicle and ...

See Is it OK to replace only 2 tires on an AWD car?. If you call different Audi dealers you're likely to get differing answers regarding how much tread depth difference is OK for the all-wheel-drive system. Nonetheless, I would advocate calling to get specific recommendations for your vehicle, as some all-wheel drive systems are more sensitive to ...

It may not be apparent right away but may cause issues later on. The Limited Slip Differential contains clutches. They require oil with an additive that allows the clutches to operate correctly. Check the container that the oil came in, it should say Limited Slip/ Posi-trac compatible. It may be in small print on the back of the bottle. If it doesn't, you ...

This could work in a car with an open differential and an active traction control system. When the system detects a wheel spin, it actively brakes (and locks out) the particular wheel, as a consequence the torque is directed by the differential to the wheel with traction (least resistance, as you noted). I do not know the details of the implementation in ...

Your best bet is check out the assembly with your Mercedes dealer. They may be able to tell you what vehicles your differential assembly was fitted to. If you are not intending to buy new, then a list of vehicles it was fitted to will enable you to carry out a broader search for vehicles from vehicle dismantlers.

Detroit lockers aren't the most streetable differentials, but they should be a little easier to deal with than what you're describing. Two things: 1- That's a lot of play in your driveshaft and it sounds like too much to be incorrectly set backlash in the ring and pinion gear. Are your u-joints and carrier bearing (if you have one) ok? While you're checking ...

If your limited slip differential has started to mis-behave then you really should take remedial action, it has become dangerous by virtue of being unpredictable, and it can only get worse. Depending on age and mileage you are looking at a replacement unit. You pays your money and you take your choice of which one. Overhauling a high mileage unit piecemeal ...
