bp17oang Posted March 5, 2021 Author Share Posted March 5, 2021 4.10 is the carrier split, so it is a different animal than the 3.55 I'm not following that... Link to comment Share on other sites More sharing options...
ArdWrknTrk Posted March 5, 2021 Share Posted March 5, 2021 I'm not following that... A 4.10 (and up) ring gear uses a different carrier than 3.23, 3.55 3.73 ring and pinion sets. The gear is bigger because there's not enough room to put that many teeth on a smaller diameter blank, and the teeth for a lower numerical ratio would be too wide on a 4.10 and up gear blank. The pinion won't work then.. So, we call that the carrier break. It's not an issue if you're not regearing. But plenty of kids with a 150 that want big tires or a rock crawler don't realize that they won't fit. Ooops! Swapping the whole chunk is not an issue.

bp17oang Posted March 5, 2021 Author Share Posted March 5, 2021 I'm not following that... As it's currently constituted it has 3.55. But as you can see I acquired a 4.10 assembly before I got my senses on what I should be doing. Link to comment Share on other sites More sharing options...

I just never heard it called that, but I was aware of that differences you describe. Anyhow, that's all water under the bridge at this point Link to comment Share on other sites More sharing options...

ArdWrknTrk Posted March 6, 2021 Share Posted March 6, 2021 You're up working early. And making good progress, I see! I hadn't thought about having to cut the lower frame channel to clear the shackles. Do you intend to box the front of the rails like your 250? While you're in this deep you really should check that no frame cracks are forming between the two rear steering quadrant bolt holes. And that the Huck bolt and forward crossmember are tight on that side. (Ask Gary ) Link to comment Share on other sites More sharing options...

And that the Huck bolt and forward crossmember are tight on that side. (Ask Gary ) Yes I had to cut the bottom lip of the frame for the shackles. I also welded shims inside that hanger. The 4wd had a "recess" on each side where that top shackle bolt goes through. It's also relatively close to a notch on the frame so hopefully that strengthens it up. The driver side is boxed in the same as the 4wd where the gear box mounts (Edit: upon looking closer you are correct that it is boxed in a little bit less on 2wd. Looks like a chore getting that entire section out so I might just fab some pieces in there if necessary). I did weld the piece in from the passenger side which hopefully you can see in this photo. I figure I will go ahead and put the bracket in that the TTB sway bar mounted to. Not sure that really will help hold anything together but I guess it won't hurt. And yes, I will absolutely be checking those things out before dropping the motor in. Thanks for mentioning that! Link to comment Share on other sites More sharing options...

And Jim is right, check out the frame where the steering box bolts on - Dad's was cracked there in spite of having been treated kindly all of its life from what I can tell. And on both trucks the huck bolt was loose. Link to comment Share on other sites More sharing options...

And that the Huck bolt and forward crossmember are tight on that side. (Ask Gary ) The front hangers were not too bad. The three holes for the core support are used so I could use that to go off. The rear ones were a little trickier for two reasons... One, no holes matched to work from, and two one hole is up under the cab mount. So, I measured everything based off the 4x4 cab mount from several points with a caliper etc. Then I made a jig based off the holes I could drill that I could reverse to mark and drill that particular hole from the inside of the frame. Edit: also I think there were two but at least one huck bolt on both sides that I had to cut off and put bolts in due to having to take off the mounting system for the coils. I will double check that Link to comment Share on other sites More sharing options...
