    Rear Main

    The exhaust bolts are not all that hard to remove. I would soak them with pb blaster and use impact. They will be off before you know it. There is 1 nut on the passenger that you will not be able to get to unless you remove the o2 sensor. I didnt touch my barbel. usually if it protrudes or...

    Steering Rack Replacement

    I am about to try to tackle the same job. Can replacement tie rod jam nuts be purchased locally?? I was wanting to pull my rack with the tie rods still on it so I can compare to the new rack. Do your rack come with new o rings?

    Help Diagnosing Oil leak

    Well the oil plate gasket seems to have cured most of the leaking which would make someone think its the rear seal. Oil was streaming from the plate to oil filter area and blowing near the inspection plate area. This leak somehow just had formed. And I did notice my oil pan gasket seeping from...

    Radiator/transmission question

    I doubt the transmission sustained any damage just driving a few miles limping it home. I would scan the truck for codes and start from there. Misfires will also cause the service 4wd to display
