Does it do it every time, and only on the 1-2 shift?



If you just shift from P to D to R and back to P, any noises heard then?

First guess would be isolator bushings, though it would be odd if it made the noise ONLY on the 1-2 shift.

The rfe can have a hard cold 1-2 shift I have noticed... that would make the front diff clunk if the very common isolator bushings were toast.
