Today i started coop at a local gmc chev pontiac dealer and i worked on a 2003 2500 hd. it has only 12 000km but already is having some pretty major rearend problems. we had to replace the clutchpacks and ring and pinion. I think this is rediculous as its almost brand new. This is just Testament to the crap quality of chev driveline's.

 

So you just started working there and you saw one truck with a problem. From that you extrapolate that chevy has crap drivelines? I owned 8 chevy trucks, the last one being an 01 2500HD 4x4 dmax/allison, before buying my 03 Excursion and I never had one driveline problem with any of them. I'd say ford has a worse track record than GM when it comes to drivelines.

 

There has been more than one truck with this problem there has been about 10 trucks in the last month with the same problem.

 

Why didn't you say that in your first post? 10 would maybe indicate some kind of problem but I'm sure you'd have said that in your first post to bolster your arguement if you'd known about it. If you didn't know about all 10 of them in the first place, it wouldn't really indicate "crap quality of chev drivelines". Something doesn't add up.

I follow some big GM forums and I rarely see posts about rearend problems.

 

Well if you think that Ford has worse drivelines, tell me why many race cars out there run Ford 9" and 8.8" rear ends, and why so many racers out there use C6 and C4 trannies.

 

Yeah i haven't seen to many chev raerends out there at the track or offroad under good trucks. The ford 9 inch owns all forms of racing from the strip to the oval to the dirt.

 

This thread was not about racing or race cars. That's a whole different ballgame.

 

Ok then, when I am at the junkyard, I see thousands of GM rears going into the crusher, and the 9"/8.8" rears being sold. Thats good enough for me.

 

Well, that's nice and all but, again, that's not the subject.

 

Yeah but it just shows that ford rearends stand up better than general motors rearends. In the end if it wins on race day it must be better to begin with.

 

I disagree. Are we all running NASCAR motors in our vehicles? Racing has a whole different set of demands that aren't often practical in the real world.

 

Are you not listening?
They hold up better in the real world too. I gave my example, and thats hard to beat, because in the end all cars end up in the junkyard, and when metal comes to metal, more gm rears go into the crusher and more 9"/8.8" rears go back on the market. They hold up better.

 

I'm listening. Are you? Racing is not the subject. Maybe ford rearends hold up a little better than GM over the long haul. Fine. Good for the junk yard divers. I'd bet the vast majority of those GM rearends going to the crusher were still good, too. Apparently the Ford rearend, from what you say, is better for racing but they all reliably serve John Q. Public getting to work everyday.

But the subject is "crap quality of GM drivelines" which has not been established.

In the first post, he only mentioned one bad rearend and extrapolates that into some trend. Then it magically turns into 10 (nice round number) in a month (he'd only been there 5 days) when I call him on it. So if I walked into my ford shop and saw them putting a tranny in a newer Super Duty, can I say that's a testament to how horrible the drivelines are on Fords?

Defects happen to every brand. Take a look at the 6.0 diesel page on this forum. Brand loyalty is okay. Brand blindness is another story.

 

My dad worked for a Chevy dealer when the duracrap came out, EVERY one of the first ones they sold came back because IT COULD NOT TOW! They had no power. I just watched an episode of Trucks today where they dynoed a duramax, 195hp at the wheels and 350ish torque......... That's kinda weak if you ask me......... Also the fact the scrapyard save the Ford rears and pitches the GM ones indicates which there is a market for. And yes most of the new engines in our trucks are directly related to the nascar and indy car engines. This is where most of the newer engines start out is at the track. If they do well then they get passed on the consumer.
