    2.5 Ton Axles for 1974 K20

    I've made a decision to get rid of the wimpy 10 bolt in the front of my K20. The truck already had 37" mil tires, however I am probably going even bigger since the truck is now taking an 8" spring lift. I originally looked at a D60 for the front, but after researching them, and reading some...

    Differential setup

    Ok...well considering that Iʻm a rookie in this realm...it sounds like most of yaʻll are saying I should clean off the existing compound, buy some new compound, which apparently Iʻm gonna have to go through Amazon to do instead of being able to get it today :(, thin out my compound with ATF, and...

    Differential setup

    Hey fellers...need some insight and opinion here...take a look at these pics and you fellas tell me where you think I'm sitting. Backlash is already at around 5 thousandths...just trying to get contact pattern in the green.

    Gentlemen, take a look at this wierdness...odd "crack" in diff housing

    Alright, my buddy put me in touch with an axle guy...Iʻve been right all along. Itʻs a non-issue because all that area is is shaft pass-through. All I need to do if I want to feel good about it is what I said...light deburring and continue. Sorry to bug you guys. Iʻll leave the post here in case...

    No...Iʻm not talking the seat for the race. Let me see if I can take the picture and circle the areas Iʻm talking about.

    Gentlemen, take a look at this wierdness...odd "crack" in diff housing

    Got the axle housing emptied out for rebuild and was cleaning it up this morning. After some cleaning, I noticed the "cracks" youʻll see in the pictures. Now looking at the drivers side, that one looks like itʻs there for a reason, cast during manufacturing. The passenger side however...

    8.5" 10 Bolt Outer Axle Seals / Modification

    Iʻm specifically asking about outer axle tube seals for a 10 bolt front. Iʻve found them for D44, but parts arenʻt interchangeable until knuckle and out from what I know. I just cleaned my tubes out and it had a massive buildup of mud and gunk that I had to clean out. I would really like to...

    GM 8.5" 10 Bolt Rebuild / Knowledge, Opinions, and Advice Requested

    I totally forgot to ask this one though. Is it ABSOLUTELY necessary to replace ALL steering arm fastening parts? Studs, conical washers, and nuts?

    GM 8.5" 10 Bolt Rebuild / Knowledge, Opinions, and Advice Requested

    Sweet! So far I'm on the right track then. I've just about got the 10 bolt for the front done and buttoned up. I'm just waiting on a few parts to finalize it. I mainly went in to both of them to inspect and change the wear items like ball joints, bearings, races, seals. I got these axles along...

    GM 8.5" 10 Bolt Rebuild / Knowledge, Opinions, and Advice Requested

    As I've mentioned in a few posts already, I am rebuilding a 14 Bolt axle that will go in the rear of my 1974 K20, and a 8.5" 10 bolt that will go in the rear. I wanted some different perspectives on a few things. I am NOT a rock-crawler, and nor do I intend to be with this truck. This will be...

    Front 10 Bolt Axle Assembly

    Ok, now that I've seen someone else mention the sleeve protruding through the bottom quite a bit, like mine is, I have to ask the question. Is it a problem if that sleeve is protruding through the bottom?
