Front end brakes/wheel hub. I bought this truck from a friend at about 125,000 miles back in 2009 for $1200. It's been a decent little truck. I do have the V6 4.3L engine. Best feature about this vehicle. Something about the front end, driver's side hub/wheel bearings...spindle etc...on my third one. One of the worst features is the electronic dash instrumentation. Lights going out, shorting out, blinking on and off...possessed like. If you're mechanical, have a place to work on it, and would be a 'truck' back-up vehicle this is a good little truck.
91 4x4 4.3L swb 3rd owner. These years of trucks were the last of the trucks that were not yuppie-fied. I bought the truck had to replace engine (due to my driving style) new clutch new tires and breaks. with all that still like the truck the lack of performance and poor fuel econ keeps me from speeding. And its size keep the truck needing friends at bay. I know that it sounds like I don't like my truck but I do very much. I hope to have my kids learn to drive in it because the prev mentioned reasons and it is old enough to not be concerned with the expected body damage.
This makes my second '91 S10 pickup. My first one I bought new in '90. The only reason I got ride of it was I moved to a big city and was told I did not need it. I could kick myself for not keeping it. First one I had not one problem with it kept her 5 years. This one I have had 5 years she has over 200,000 miles on her and she is still going. Wouldn't trade for anything else but maybe a new one. I have done everything from halling rocks to making long road trips in her. Other then general maintance she has been a wonderful automobile.
