Tomorrow I'm going to look at a 92 GMC Sierra 4wd that's for sale. It's a regular cab, short wheel base with the 4.3 and 5 speed. The engine has been rebuilt, and the clutch was replaced 15,000 miles ago along with some transmission work (?). I plan to drive it both in 2wd and 4wd to see if everything seems OK. Is there anything that I should know about these trucks, and anything in particular that I should be looking out for other than normal wear? I'm only going to drive it to work every now and then, mostly when the weather is bad and my wife needs the Tahoe to drive to work. Any advice would be appreciated!
