#5198 of 6471 Rust issues on GM Vehicles
May 03, 2005 (7:41 pm)
I recently purchased a used 2002 Yukon (Wanted a Tahoe but got this Yukon instead) I had it for a few months and one day I noticed bubbles in the paint along the folded seam on the rear hatch... this caused me to look at all the seams on the doors (at the bottom) and the hood... They all had the same rust issues. I didn't look as closely as I should have when I purchased it... as it was a "Certified GM Used Vehicle..." to make a long story short... I had to fight a little to get the local GM body shop to fix it... or should I say post pone the end result... It has only been 2 months... and the rust issue is back on the hatch... I started looking at other Tahoe's and Yukons to make a trade to get rid of this rusty vehicle... only to find that everyone I looked at... was in the same condition... I looked at 3 2003's and 1 2002. I even checked my friends 2003 Chevy truck... and his seams in his door are doing the same thing and he does not drive his truck in the winter and only has about 15,000 on it... he keeps it more for show than anything. Just wondering if anyone else is having this problem. Thanks.

Aren't our hatches aluminium?

I don't know where you are geographically, but I don't think I have ever seen rust on a GM truck or SUV here in central Texas. And there are a lot of them around!

These vehicles have all been looked in northern OH, PA and NY. I realize we are in the "rust belt" but on a vehicle that is only 2 years old... and not driven very much... to have rust in the seams of the doors... it just isn't what one would expect... don't get me wrong... I love the Yukon and Tahoes... best looking vehicle on the road today.. I like everything about it... except the fact that it has rust issues. My other GM products never had these issues even when they were 7-10 years old. Thanks.

My 2002 Tahoe does the same thing and the oil is at the correct level. However, mine does not leak enough fluid to dip onto the floor. The front axle assembly does not use transmission fluid. It uses gear oil. If your front axle oil has been changed, make sure they used the correct oil. Transmission fluid is red in color. Gear oil has a distinct smell.
#5203 of 6471 2001 transmission hard shift
May 04, 2005 (5:59 pm)
I may be one of the millions with this complaint...but my dealer keeps reassuring me there is nothing wrong with my 01 tahoe LT 4x4 transmission. I have a very frequent hard shift from first to second gear-regardless of the terrain (coupled with the "clink" noise). When the tranny is cold, it even lunges a little when trying to shift. At times the transfer case seems to have a vibrating noise coming from it. The dealer has checked it all out, and said nothing is loose. Anybody with this same "complaint" about hard shifting and what can I do?

Wow, yeah the symptoms you describe could happen due to having different axle ratios on the front & back. The easiest fix IMHO would be to swap back a facory rear axle (locking or not doesn't matter, just go 3.73) since the front hasn't been changed.
There's a way to figure out the ratio, but you'd have to find the specs. You should be able to match rpms & speed to a specific rear ratio. I don't know of the top of my head how to do this or where to find the factory specs. Sometimes they're listed in service manuals.
#5205 of 6471 2004 Tahoe gas mileage
May 05, 2005 (9:27 am)
I bought a 2004 Tahoe 4.8 L last November. My wife uses it primarily in the city. We only have about 4k miles on it but the gas mileage really sucks. I have been reading about this on the boards but I think my mileage is so bad that something must be wrong. I am only getting about 11.5-12.5 MPG. Has anyone else seen their mileage this bad? We do use it on the highway about 20% of the time and the mileage remains about 12mpg. What can be the cause of this? What are some of you experiencing as far as miles goes? Please give me some feedback. I love the vehicle but the mileage really should be this bad should it?

I have had 2 Tahoes 2003 LT, and 2004 Z-71. My LT was 2wd and it had a problem of a delayed shift from 1rst to 2nd gears. It would begin to try to shift, but be slow about making the entire shift, then suddenly a distinct bump would occur as it finally made the shift. It felt like someone had tapped my bumper from behind. Never got it fixed, so traded it in when it got 36k miles for my 2004 Z-71.
The Z-71 is 4wd and it has always had what I call "slop" in the drivetrain. It feels like my old 76 Camaro when the Universal joints would wear out. It shifts harshley especially when not under load, such as letting off of the accelerator in the parking lots. Frequently there is a distinct Metallic "Clank" with the shift as well. My dealer installed some extra lubrication yoke which really did not fix it. At the same time they reassured me it is a common issue. Almost common enough to reassure you you have a GM truck just by having the problem.

Thanks for the info Alan, not many American axles knocking about here in the UK so I will order a new 3.73 ring & pinion from my local American parts dealer & swap it for the one that is in there.
