need to replace pinion seal on differential.A regular socket does not
work.Is there a special tool or do I hunt down a thin wall socket?Thanks

Whenever my engine is on idle it starts to rev up and down and the car
shakes from the revving. The engine light comes on and I can smell rich
odor from the exhaust. Please help me on advise. Thanks.

Have an '04 325xi, 10K miles, driven daily. Brake friction noise has
always been audible since new, just a rubbing sound seemingly from the
pads. Dealer checked them and said the were fine, and just changed the
fluid.
