Sometimes you can get some squeaking for friction betwean the leafs.
You have a 2 leaf rear suspension with a extra leaf for a booster. so
it can flex a lot in normal driving. What you could try to do is to
jack rear up to unload springs and then spray a lubs between the two
main leafs. YOu want a sprayable grease or lube that is heavier than
WD40 and do not use a silicone spray either. If the leafs is the
cause, this should cure it for a long while.
Thanks snow man and Brody
I got my truck undercoated and it was sqeeking before that, but they are
blaming the oil.The dealer told me that if I put any oil ,lube or what so
ever they will no longer warenty this portion of the truck. They are telling
me that the oil is causing the rubber to swell ant that is the sqeek. If any
body with the same problem please post here so I could have some feed back
the show the dealer that I'm not the only one with the problem.
If the squeak is in the leafs themselve, use a petro based lube, if it
is in bushings, you could try silicone. (do not worry about deal
threats on warranty as it is without merit) One more thing, you could
try removing cross bolt nut from each spring end (do not remove bolt)
to remove preload tension on bushings (because they are installed hung
and unloaded) and then tighten them back up and see if the helps. Also
be advised that there is not much spring back there and there is a lot
of flex from axle torque because of this and it is made worse yet if
you have bigger tires.
It is stock tires but my truck is going in tomorrow 24 august and I will
know more then.You happen to know alot about warrenties and Chevies. Do you
work at a Chevrelot Dealership?
Keep the suggestions coming
No but I have a few friends that are high up in the food chain with
them (I always get a new loaner truck fresh off the lot when I need
one and I have had a LOT of different ones from P/Us to Avalances to
even new diesel dump beds) I have also befreinded a few good techs
too. (they used to run street rods in 70's like I did) I have made
several chevy warranty claims on my 2000 K3500 in only 37K miles and I
know there weaknesses. I use trucks as trucks and for plowing snow too
and I know what you can do to them and not hurt warranty.
