RacingDiffs differential bearing set - Differential type 188mm for BMW (E30, E36, E34..)

These sets are suitable for most differentials up to year 1999. You can recognize them by bolt-on side caps that hold the carrier unit. Unlike K, L and LW types which have C-clip design, millimeter differential types have shims between housing and caps.

Millimeter differential type was found in following models:
- 3 Series: E21 (big case), E30, E36
- 5 Series: E28, E34
- 7 series: E23, E32, E38 (early models)
- 8 series: E31- Z series: Z1, Z3, Z8Z1, Z3, Z8

You can choose 3 different options according to your differential size.
Simplified, 4 cylinder models use 168mm differentials, 6 cylinder are 188mm while 8 cylinder models have 210mm differential size.

How to tell if your differential needs bearings replacement?
Characteristic noise from differential/transmission occurs during acceleration and coast (engine breaking). To distinguish differential bearing noise from the wheel bearing noise steer left-right like you are warming up tires for the race. If the noise changes its intensity then it is a wheel bearing. If intensity of the noise remains the same, that means differential bearings needs to be replaced.

Each set includes:
-1x Crush sleeve
-1x Small pinion bearing
-1x Large pinion bearing
-2x Side bearing
-1x Input flange oil seal
-2x Output flange oil seal
