Re: strange noise by rearend
that noise you hear is the
cant be more clear than that can it?
if you look under the car, driverside, just in front of the axle where about where the brake line on the chassis changes to the rubber flex hose to go to the axle, there is a white vent fitting there attached to a bracket ont he frame. It vents/bleeds pressure or vacuum from the tank and makes this noise after you turn the car off aster running it.
if its not that, idk what it would be.

Re: strange noise by rearend
Yea mine sounded like it was going to rattle its way out the tank. The one in one of my trucks squeeled like a little girl right before it locked up. The last one in my current truck just keep pumping and pumping and never wanted to shut off. Sounds like i have bad luck with fuel pumps, have to think about that for awhile.
