I just turned 190,000 on my 2000 4.8 ECSB with original motor and tranny. Rear end has been changed and brakes, but that's about it. Piston slap in the morning, and the fuel pump whines and gauge reads wrong, but that is being fixed shortly. I am going to drive this truck until the wheels fall off. It is paid for and I am trying to pay off student loans first then new truck next.

If I might ask, how much did that run you, and do you do a lot of towing?

[silverado122775]

about $2000 with labor.. the rear-end itself was about $1350.. axle's not included.. I was lucky enough not to need to buy those..
I do not tow all the time.. but the truck as worked it's ass off numerous of times.
It was really weird.. I starred hearing a loud bang with a jault when making left turns.. first it was not all the time but got gradually worse pretty quick.. I took it in to a friend's friend. (to make a long story short) it finally busted when they tried to get it to the dealership. They quoted me $3200. The dealership will not replace the whole rear-end.. they insisted on buying each part separetly. So I took it to another place who recommended the Jasper rear-end.

At 39,000 miles I lost all gears except 1st. and 2nd. No reverse, no nothing.

Chevy made me pay about half of the $1200 repair.

Motor is strong... Mobil 1 every 3-5K miles

Another reason why it pays to find a reputable mechanic that can do quality work for much less than the dealership.

On the rearend, do you still have the same gear ratio, or did you change that?

[silverado122775]

I wanted to, but then I would have to change the front as well. but I did not have the extra $$. The option I almost went for was to go with a POSI rear end. but again that cost extra $$ too. only an extra $200, but it was still too much for me. I know I will kick myself in the a#% later for it. LOL
