    adjusting driveshaft, pinion angle

    So with where it is now if I take 3* out of the pinion to move it up and have less of an angle the driveshaft will change angles at the transfer case side. So do I shim the transmission up more or let the angle change?

    adjusting driveshaft, pinion angle

    Stupid question but does the driveshaft have to be pointed down in relation to the transfer case? If I take out my shims it will get the pinion side about right but it’ll push the pinion up and the driveshaft will have an upward angle at the t case and downward angle at the pinion.

    adjusting driveshaft, pinion angle

    And by raising the transmission do I have to worry about the angle of the front driveshaft?

    adjusting driveshaft, pinion angle

    So long story short I lowered the rear of my truck an inch more and I cannot get my driveshaft angles correct. I shimmed the rear of my transmission up and have shims under my axle. So the driveshaft was pointing up then would get to the pinion and I have a 6* angle there. I had a slight...

    Getting truck smogged problem

    You can swap engines as long as it’s the same year or newer. Not sure how to go about that process.

    Can you see what the OS is in the tune that’s in it? Then just pull one off of here that matches.

    Getting truck smogged problem

    The the tune has the operating system which that has to be correct or you’ll have issues. The calibration for the engine I believe. You can make changes to the correct tune and the smog equipment won’t know. But switching the tune to a DSP changes the last digit of the calibration to a 5 and...

    LB7: Should I be scared to buy an LB7

    I would get an LLY if possible but if you’re okay with changing injectors there’s nothing wrong with an LB7

    It doesn’t have to be a stock tune but a stock calibration is needed.
