    NP203 leaking. Replace or fix?

    For $100 I would grab it. If you need the truck to drive every day then I would rebuilt the $100 unit and swap it out. That will be fastest. If your truck is not a primary vehicle and you can live without it while you work on it. Rebuild the $100 unit first, then do the one in your truck. This...

    NP203 leaking. Replace or fix?

    I would take it apart and reseal it. The speedo adapter has a little seal in it. The output seal is most likely leaking due to a grove worn in the flange. You can replace the little speedo seal really easy. The output seal is pretty easy too. You want to get a kit that has a repair sleeve. Super...

    Nylon cam gear years

    I just replaced the timing set on my 1987 GMC. I have owned it since 1988. It had nylon teeth on the cam gear.

    R4 Compressor Help

    Four seasons says to add the oil to the compressor then stand it on end for 1-3 minutes to lubricate the front seal. I would doubt the shop is doing that. Also if your compressor had a mechanical failure debris may be floating around the system and taking out the new compressor. You should...

    Have a great Snap On dealer finally

    I had a composite dead blow hammer I bought in the 90s but hardly used. I grabbed it last winter and it shattered. I gave it to a friend who still works in the shop. The Snap-on man replaced it. He also replaced some broken picks and screwdrivers. When I bought my backhoe I needed some 3/4"...

    Are these dual shocks factory. Pic inside. 1987 K10 long bed truck

    Monroe/NAPA has different shocks for quad suspension. I bought my shocks at NAPA for my '87 V3500. They seemed so wimpy and they did not fit right. Went back to NAPA and the counterman said "You have quad shocks, right?". "No, I don't". Got the correct shocks and they were much beefier and fit...

    Unconditional warranty means just that, no conditions. It broke, replace it. Craftsman used to be good years ago about replacement of broken stuff. When my Dad passed a few years ago and we clean out his workshops I find a dozen or so broken Craftsman screwdrivers. Took them to Lowe's and they...

    Have a great Snap On dealer finally

    You buy a franchise you have to honor the warranty. The warranty is not paid for by the franchisee. The franchisee has to do the paperwork and they don't like that. I have called Snap-on corporate a few times when I had my business to get them to honor warranty and stop occasionally as we needed...

    Wobbly power steering pump pulley

    That is the problem with rentals. My puller is a Snap-on I bought in the 80s when I worked on Fords. It does Ford and GM pulleys. Hit up eBay and find a good one there. OTC, Mac, Marco, Snap-on, Cornwell are all good names.

    Have a great Snap On dealer finally

    I see techs with $30-40,000 tool boxes. There is almost no tools in them. They are paying 22% and higher interest rates. Absolutely silly. the majority of my Snap-on tool were bought used. 40 years later I still have them. The dealers use to hate me because I would not buy tool boxes. They also...

    Have a great Snap On dealer finally

    Snap-On hand tools are great. Their air tools, electric tools, and other things are not so great. Snap-On sockets have a thinner wall than other brands. 99% of the time that doesn't matter but when it does....... @Ricko1966 I used to tell new guys starting out. Go to Sears and buy everything...

    Brake Fluid Flush GMT800

    I am with @Ricko1966 on this. I have never seen a swelling brake hose in my 40 years in the service business. Plenty of internal issue causing a blockage and brakes to drag. I have seen brakes that got so hot that the fluid boiled. This made air bubbles in the fluid that had to be bled out...

    Brake Fluid Flush GMT800

    suck the master and refill that with clean fluid then just bleed old school. You should do this at minimum every two years. Brake fluid is hygroscopic. Beside the obvious damage water does it significantly lowers the boiling point of the brake fluid. So when you need your brakes the most the...

    Alternator amps

    As Rick says if you know the right combo you can get what you want. The issue with parts stores now-a-days is they rely solely on the computer. So when you come at them with something not stock their heads explode. If you have an old school store around they typically can deal with requests like...

    Have a great Snap On dealer finally

    That is good news. Tool dealers are hit or miss. All my hand tools are Snap On. After 6 or 8 years I stopped needing to buy stuff and occasionally needed something. The Snap On dealers would stop showing up and then give me crap about replacing a broken tool. I used to have to do what you did...

    Alternator amps

    My '87 GMC has the same alternator. The model is a 12Si. They came in a few amp ratings but all were physically the same size. So go with a 94amp unit. I recommend Bosch AL559N. It is new and carries a lifetime warranty. You will have to swap the pulley. CS130 alternators are great but they are...

    Wobbly power steering pump pulley

    You will also need an installer to put the pulley back on. They are also cheap.I could not find my installer. I have/had a Snap-On one I bought in the 80s and haven't needed it in 25 years so god only knows what happened to it. I just picked up a brand new unit off eBay. Military surplus brand...

    Searching for My Dad's 1979 Chevy Suburban

    That speedo gear is not what I am used to seeing but I never played with trucks much in the old days, only cars. A little searching and it appears that is the driven gear and the drive gear is plastic. My truck has an NP208 transfer case and uses the little plastic gear. Turns out the NP203 and...

    Practice welding a lot before you try welding on your truck. Go buy some 19 ga metal and get good at welding it. Vertical, upside down and on the flat. It take a ton of practice. If you are welding outside consider using flux core. Yes, you will have to chip slag but a little breeze won't mess...

    Do I restore my AC or?

    I thought G bodies were 1982-1987 and A bodies were 1978-1981? Not that it matters. I may be wrong. I was a Ford/Volvo tech in the mid80s.
