Silverado?

First post here, I have the chance to buy a 1999 Silverado Extended Cab with 140,000mi that is definitely NOT stock. I was wondering what kind of maintenance I would be looking at considering the strain that a modified suspension and oversized tires puts on the drivetrain, motor, etc?
The truck has a 6" Fabtech lift, 3" body lift, and 38" Thornborugh(sp) tires. The motor has a K&N intake, throttle body spacer, chip, Gibson headers, and dual exhaust. There are numerous other modifications, mainly for looks. The previous owner replaced the rear with a locking diff and 4.56 gears. If anyone has any input on this, or have had any troubles, please help me out.
Thanks

Re: Silverado?

Well, unless I knew the owner and how he did all the work, I wouldn't buy truck modified that much. The truck has 140K, it seems to be kept up well enough to put on that many miles. You'll have to know what you're looking at so you can see if things are up to par.

First off, much stuff was put on for looks...ie, the Thornbird tires = crap. And 38s no less. Don't perform well, but they look cool! [img]images/graemlins/thud.gif[/img] Fabtech lift, I don't like, but make sure everything is snug and tight as far as hardware and geometry goes. Check your CV joints for angles, check the ball joints for angles and wear, check yout tie rods for movement and slack. Check the steering link and pitman and idler arms for slack. Check tire wear for alignent. The body lift...blah, again, I don't like, but make sure all body mounts are straight and the bolts are tight. Check the bumpers to see what was done to adjust the height back to level with the body. Check the radiator fan shroud and such to make sure that was all put back together after the body lift.

The engine mods, K&N filter is common, just check in there to see what it looks like. The chip, I'm not a fan of and really couldn't tell you want to look for. What kind of chip? The TB spacer, again, not a fan of. But check to make sure there are no gasket leaks. Headers, make sure they're on there correctly and check gaskets for leaks. Chances are, there will be one, or one will develop. That's pretty typical with headers. As for the rest of the exhaust, check for leaks, rusting and routing.

As for the drive train, the rear was worked on. Make sure the locking diff works. Ask who did all the work on the truck? Make sure you ask. How long has everything been on the truck, it matters. Listen and feel for slack or vibration in the drive train.

Forgot to mention, check all the fluids. Check the oil, check the tranny fluid. Is it dark, smell burnt? Check the diff fluids. Is it clear and clean or does it look like a milkshake? Check all the seals, any leaks?

Re: Silverado?

Thanks for the reply Shorts.
I'm pretty sure that most everything major was done professionally. The lift kit looked alright from first glance, the dual front shock mount looked kind of rusted, but I am going to beadblast and powdercoat it, along with the rear link and any other parts that may need powdercoating. I didnt get a chance to look over the engine to check for leaks, but I will definitely go over the whole truck whenever I go look at it again this week. Hopefully, if everything goes alright I will have it by Thursday and have pictures posted by the weekend. Its a pretty nice truck if I do say so myself.
Thanks

Re: Silverado?

Wow, very thorough there Shorts. One thing I couldn't glean out of his post was if the truck is 2WD or 4WD, if it's 4WD, make sure the front's been regeared to match the rear. If it was a pavement pounder, might have original gears.

Re: Silverado?

It is the 4x4, and the previous owner hasnt regeared it, which will be something that I will do eventually. He just took the front drive shaft out. Does anyone have any idea what kind of price I'd be looking at to regear it?
Thanks

Re: Silverado?

$350-$400 in parts, probably. Labor varies, look in the yellow pages for gear/transmission shops (near you) that work on axles, they could probably give you a good estimate.

Re: Silverado?

haha you covered it. I remembered that when I was typing another part of my reply, then when I finished typing, I forgot what I was thinking next [img]images/graemlins/crazy.gif[/img] When I was inquiring abour a regear for my truck, I think I was quoted about $90 for the install kit and another $250-60ish for the work. And that was with me supplying the front R&P. You could be able to find a decent package deal that will keep you under $450.
