Hi, I just thought I'd introduce myself. I've just picked up a '97 GMC Suburban 2500 SLT 3/4 (HD version) with a 454. 106k miles. Two-tone blue and white. This is the first truck I've had and the first American made vehicle I've owned (I'm here from the UK for a few years). The last cars I did any work on were small, light, front wheel drive and stick shifts. I'm pretty clueless regarding much of what I've just bought. So far the (future) job sheet looks like this:- Fix front wheel shake under braking - new pads and rotors and possibly new hubs while it's all apart. (DIY - but scared of those 15mm hub bolts) New tires (Michelin LT M/S2 I think will work best for me) Get the aircon sorted (It's still 70+ in the Bay area at the moment) Pitman and idler arm (probably going to pay someone to do that) Transmission, transfer boxes and diff fluid changes - (pretty sure these have not been done for 10 years - 30k), I'll do this myself. Fix a few small leaks - possibly oil cooler lines, definitely one of the valve covers, maybe the steering pump - none of these are too bad. Tune up - new plugs leads and distributor cap Fuel Filter Air filter - do those fancy cold air ones really help? Hopefully that's it.
