    Check for rust in the usual spots (bottom of the fenders, under the battery tray, above the rear wheels, front floors)

    Mileage?
    does the clutch slip, chatter?
    86 should be a hydro cluch(does it leak anywhere)
    check the color and condition of all the fluids and hit the owner with a low offer,LMAO!!!

    and make sure the front is indeed the Holy Grail AKA "Dana 60"

    Are you going to surprise him and buy one? Sounds like a good choice in trucks if it is in good condition. I wish my wife woke up one day and wanted a 4x4. /forums/images/graemlins/waytogo.gif

    there is only one thing you need to look for on that truck... the Dana 60 front. You can identify it by looking on the lower right corner of the front diff. there will be a marking stating "D60F". Here's a link to the axle identification chart to help you more. axle I.D. page Other than that, make sure the engine runs and there isn't a lot of rust. Everything else is an easy fix /forums/images/graemlins/waytogo.gif

    Just out of curiosity, how was that truck for smog equipment? Out here in CA, 86 was the last year of carbs on these trucks and the absolute worse for smog. I know guys with 86 GM trucks that haven't been registered in years cause they can't get then to pass smog. It's hard to give an 86 away in CA. I'm wondering if other states had less smog equipment requirements in 86 than CA? If not, I'd say you got lucky letting this one get away!

    If it is indeed a 1-ton BUY IT! You can verify it by ID'ing the axles as a Dana 60 in the front and a GM corporate 14-bolt in the rear.

    -Check the fluids for cleanliness to indicate good maintenance.

    -Check that the eninge doesn't burn excess oil or any coolant by observing the exhaust upon start up and upon HARD acceleration, esp when the engine is under high load (like after a shift).

    -Verify that the engine is operating at a normal temperature. Old 454's that have a heating problem can be a real PITA to fix the overheating problem.

    -Listen for any knocks from the engine or any whining from the tranny (with the tranny in neutral and the clutch pedal OUT)

    -Verfy good oil pressure from the engine (15psi or greater when at operating temp @ Idle)

    -Check for runs in cab corners (esp. under carpet) and at body mounts under the cab...


    If you find problems with any part of the truck, simply use it as bargaining power to lower the $$$$ and fix it yourself.
