I have a '92 400E with 72K miles. I'm told the PS pump is leaking and needs a seal kit. I'm also told this is a TEN hour labor job by the MB dealer. Is this accurate? I'm also told replacing the pump with a rebuilt isn't much less of a job on the labor end. What is advised, resealing with the kit or replacing? Does this actually take ten hrs? Also front pads and rotors were changed 20K miles ago. I'm told I need BOTH replaced again. Don't they usually skin the rotors for a second set of pads before replacing? I think I'm being taken advantage of by this dealer.
