I have a '93 BMW 740iL. Great car with 224K original miles. The rear passenger door now groans when I open or shut it. WD40 hasn't helped. There is some rust on the hinge. If I remove it with fine-grain sandpaper, the rust will just come back. Any solutions?
2000 Mercedes ML 430, the brakes on this squeeks like crazy when slowing to a stop with little pressure but it howls loudly when I back up and apply the brakes.
Besides a brake job , which I was told wasnt needed, is there any spray or quick fix for this?
thanks
