ive got a 99 silverado with 210,000 on stock engine/trans. I am just wondering how long i can expect this thing to last before i get to rebuild it. How many miles have you guys seen on stock equipment? the first 100k was almost all highway miles so i think that helped its longevity. let me know what you think.

 

Someone on here has at truck with like 520,000 miles on it. It is like yours a 99 5.3. I think he said that he had to replace the tranny a time or two tho. If you take care of a Chevy, it will last a verry long time.

 

i think your lucky the trans has held up that long already. im with you around 210k miles and lost a tranny a long time ago. its all good tho, it gave me a reason to give the woman why i spent so much on a 6 speed

 

I just bought a 2003 Silverado with 169,000, runs VERY good. The tranny was done at 78,000. I HOPE it lasts a lot longer.

 

Alot of it depends on how the truck was treated... do you get the fluid changes done on schedule all the time or not?

 

ive seen an oil field truck with 315,000 miles didnt replace the factory plugs until 285,000 miles..we replaced the wheel bearings every 6 months and u joints every month

 

Do you mean the wheel hubs and not the wheel bearings? You can't change just the bearings on 99-07 trucks.

 

sorry Dick i meant the hubs

 

well you could have been talking about an obs truck. I just figured I'd be a dick when I asked my question

 

oh ok then Mark..
