[SEL] Way OT...2002 Avalanche 1500 front differential

[Richard Strobel]

Thanks Dave and Al for taking the time and effort...means a lot!

Well here's a pix of the drain plug...that's metallaic fuzz and we say in 
the aircraft world...not many chips.  There's an 1/8" dia. x ~3/8's long 
magnet in there somewhere.

Took over 7 hrs for the local Chevy dealer to call me back.  The assembly is 
no long available and have to wait till Monday to find the proper rebuild 
replacement.

I don't think a repair is in order with all that fuzz floating around so 
will go with replacement.

And Al thanks for the R&R info.  It looked like a drop-out, drop-in 
module.....do appreciate the info.

Merry Christmas all;
Rick
