    LBZ: 4WD Conversion

    For anyone finding this thread about 4wd conversions, I just completed converting my '04 Sierra 3500 to 4wd, using an '06 Sierra 2500HD as a donor truck for the transmission, NP261HD transfer case and front axle (and all the associated bits like axles, cv shafts, etc). The project is...

    LBZ: 4WD Conversion

    Just to follow up, I was able to get the original rubber bushing out of the donor frame largely undamaged by using a drill and a smaller drill bit (1/4"), and running it around the outside of rubber (press it in at the edge, between the rubber and the metal hole, then just let the drill bit run...

    Is a 6.0 okay for me?

    The middle ones generally aren't too bad to get out, with the head in the truck, but the rear-most ones can be, depending on how they are broken off and how stuck they are. But there are also third-party "clamps", that use pre-existing unused bolt holes in the head to hold the clamp, with...

    LBZ: 4WD Conversion

    probably, if the bolt hole is the same, but then you have to shave the size of the bushing down to match the holes (which, of course, are two difference sizes). and the width of it is probably wrong. easiest thing is likely to just use old take-outs. From the damaged one I took out, it seems...

    LBZ: 4WD Conversion

    and the article that led me to this thread has the answer. from http://www.dieselarmy.com/news/how-to-gm-diesel-pickup-2wd-to-4wd-swap/ "The bushings came from a frame clip he bought" Guess it's off to the junkyard for one of them, as I had just assumed you could buy new ones, so I drilled...

    LBZ: 4WD Conversion

    I know this thread is a bit dead, but did the OP buy new rubber bushings for the two mounts on the passenger side (that go in the hole that already exists in the frame, and the one that goes in the new hold you welded in)? Or did you re-use the bushings from the donor frame? The dealer here...
