Do you have to remove transmission to replace the oil pump seal like you do when replacing the rear engine seal? I have a severe oil leak that is blowing oil under the entire truck underside. I believe it to be the oil pump seal and not the real engine seal.
How do I remove the starter?
Lights flash, but don't stay on and the seats don't heat up.
The first time we had a problem we had gone to the Dr.and when we came out to start the truck it started and ran for about 15 seconds then died. It would crank but not start. About an hour later after cranking for a few it started. we had a diagnostic done on it it threw a code for crankshaft positioning sensor. We replaced it with a Napa part. As soon as the temperature outside would get above 90 degrees it would quit again. Another diagnostic and the same code came up. so thinking we got a faulty part we had it changed again. Again as soon as it got hot outside it would quit.So we talked to our mechanic and he suggested we try a Delco part that GMC vehicles will only work with Delco parts. So we ordered one. They are on nationwide backorder, so I am assuming this a problem a lot of vehicles are having. What I dont understand is why it only has a problem when the weather gets over 90 degrees. And of course we live in the cenral valley of californa and it is extremly hot in the summer. Does any of this make sense to you? Any thoughts on this problem would be extremly helpful we are just lost at this point. This truck has been such a great vehicle. Oh and btw it only has 48000 miles on it.
My 2004 3500 Duramax loses power while pulling a 35 foot 5th wheel and speed drops to about 40 mph fuel consumtion goes up and engine runs real rough. I stopped and checked trailer brakes and then it ran OK. Also if I shut the engine off for a few minutes, it runs OK. It only deoes this once or twice a day. GMC said it was fuel filter and replaced it, didn't help. They checked computer and it showed no problems. No warning lights come on I'm afraid it is going to leave me stranded one of these days. What do I need to do?
I have removed the wheels, caliper, the axle, and the screw nut in the wheel housing. I see the bearings inside, and the rotor/hub is loose, but it will not slide off. It seems like the bearings are holding the hub/rotor in place. How do I get it to slide out?

I have a 2006 GMC 3500 truck and am having problems with a loss of power. I notice this loss of power takes place when my check engine light comes on. I have had the truck looked at but nothing has been found. Is this a defect? Has anyone else had this issue, and if so, how did you resolve it? Any suggestions or feedback would be greatly appreciated. Thanks
