I just purchased a 07 Dakota Quad Cab and Im thrilled with the truck.
Unfortunately, I had a flat tire today and while I was lowering the spare, I
noticed that the drive shaft was literally covered in rust, not just
speckled, but COVERED in rust. I also noticed a few other components that I
couldnt identify to have the same condition. This cant possibly be normal
for a brand new truck can it? Im going to take it to the dealer tomorrow,
but maybe some of you Dodge fans can aleviate some of my fears....am I right
to be concerned, or is this just a "Dodge thing"?
As the rust layer becomes more established, the formation of new rust
slows down. I have only seen a few drive shafts actually fail from
rust but this was on some very old dump trucks that had very high
drive shaft loading and that could twist off a new drive shaft too
sometimes. In you application, the rest of vehicle will rust away long
before the driveshaft rust becomes a issue that weakens it to point of
failure. It kinda looks worse than it is. You could spray some rust
converter on it if it really bothers you as it will stop it and from a
black coating from it that resists further rust.
Not really. Drive shafts are not balance that close from factory
anyway and I have not seen a drive shaft yet from any brand truck that
could not be rebalnace better at a drive shaft shop even when they
were new. The deeprer you axle ratio is relatiive to tire size maakes
balance a bit more important as it increase average RPM of drive
shaft. It takes time to get them dead on and Detriot does not have
time for this on assembly line. Spraying it will have a negligable
impact on the balance of it.
Someone mechanically inclined might be able to figure out how balance a
drive shaft with a couple of jack stands, two hose clamps, and a piece of
chalk. Not that I'm suggesting anyone should go under a running vehicle in
gear on jack stands with a piece of chalk to mark the heavy side of the
spinning shaft, then put the hose clamps on the shaft with the worm gear on
the opposite side of the chalk mark, or anything dangerous like that. But it
works. Not that I'd do anything like that myself. Nope, not me. ;^)
Yes, it is rust and Dodge is not the only manufacturer that does not
completely protect the underside components. I bought a new Corvette that
was the same way. When I picked up my RAM, I immediately put the truck on
jack stands, removed all the wheels and spent 3 days under the truck priming
and painting everything that was unprotected. This also included the removal
of drive shafts, transfer case and gearbox. It took about 30 hours of labor,
but remember that you can only do this practically when it is brand new.
