I just recently picked up a 1999 GMC Yukon and I'm looking for some insight. It wasn't in great shape or well maintained to say the least, but the engine seems to run fairly well. It does need the radiator replaced and power steering pump. I'm looking for suggestions on things to check or services it may need as it has no records. I went ahead and changed the oil, but wasn't sure what else I should check.

Thanks.

 

Replace all fluids - transmission, transfer case, axles, radiator, power steering.

Check the brake fluid.

Replace belts, plugs, and wires.

Check lubrication of chassis grease zerks and wheel bearings.

Check front suspension - tie rods, ball joints, steering linkages.

Check shocks for leakage.

That should be a good start.

 

+1 for all of the above, other then I would suggest bleeding the brakes as this will give you an opportunity to inspect the calipers and lube the slide pins and you can hits those zerks while you are there

 

That's a +2 from me !

But, I'd also change out the (heater/radiator) Hoses, given the age, and new coolant as well.
