How to adjust pinion bearing preload

First, what you were planning to do isn't correct. The problem is, to correctly get the preload set, you have to measure the torque at the pinion. Also, you should NOT reuse the same crush collar if ...

Quote from one dealership, work done at another

To my knowledge, no. If they don't do the work, they don't get paid. That's even if you take it to another Toyota dealership.

A tale of two diffs: which one needs more TLC?

All three - front, back and transfer box/centre diff. As it's a permanent 4WD system, all three diffs are in constant use, so if you've got no record of them being changed, it's probably worth doing ...

Front Right Wheel locked up while driving

I don't think it's the differential, I believe it would affect both front wheels. A failed hub is where my money is, although it could still be something related to the brakes. I don't think a seized ...

Why don't FWD cars have rear differentials?

It seems to me there's some confusion about terms here. An axle is just a bit of ironmongery holding the wheels in place. The wheels can rotate independently of the axle: there's a bearing between ...

Component identification - Mini Cooper S R53 (2005) Limited Slip Differential

The R53 is a Getrag GS6 and has a 25% locking limited slip. If I'm not mistaken, it is a clutch-type. As far as a lack of information, you'll quickly find that most MINI owners just don't care what'...

Removing inner CV joint from differential

Short, sharp shock will remove it. But you need to do it in two opposing places. Get ready to be showered in fluid if you can't drain first. That's happened a few times to me!

Removing inner CV joint from differential

These are usually held in by a split ring that goes into a socket and the ring expands and retains the shaft. Yes, they can be difficult to remove. I've found that it often takes a quick/sharp shove ...

Theoretical AWD question

The main difference between 4WD and AWD is that AWD is full time and 4WD is selectable, meaning you can set it to 2WD with a flick of a switch (well, on most modern vehicles, anyways). Most AWD/4WD ...

Jack up the front end and spin one tire by hand. If the other tire spins in the same direction, you have an LSD. Examine the area next to the front differential. If you have a square housing and ...

FWD open diff car with one failed CV joint. Would this get me home?
