Hello all,

I had my car jacked up recently and was giving it a check over before a long drive to Switzerland. I noticed that the front wheels roll much freer than the rear wheels. I can still turn the rears under my own force but they are both evenly stiffer to do so. Perhaps the handbrake doesn't fully disengage but I'm not sure how to find out.

Also, I do currently have a slight leak in the rear differential. Could this make each wheel have greater friction and difficulty turning or would it be no problem at all until it locks up completely?

Any feedback welcome guys thanks.1993 520i
