G brings up a great point. It may be that you need either a better shock or your current ones are blown or not working correctly anymore. I have qa1’s and it they are all the way soft there can be some slight hop but if I turn them up past 6ish then I get no hop at all.
They changed out the diff after 07 if I recall. Think it was the year they went to the led tail lights. I have had mine since feb 24th 2006 I bought it brand new with 8 miles on it and it now has 13X,000 I will never sell it. It has become part of me and how most ppl know me.
Well finally got everything back together yesterday. I am running a slightly larger than stock rear tire and the 3.73 is the perfect gearing for me. I do a lot of autoX and drag stuff. Mileage doesn’t matter either since my truck is just a weekend toy. Going to a 3.73 isn’t much of a difference...
So just like you said I needed a different carrier. Too bad I didn’t know that before I already had all my parts but it’s ok I found a carrier for pretty cheap that will work so I’m happy. Will have the 3.73 gears and the tru-trac and basically everything in the rear brand new.
No wager lol. I’m hoping my diff guy can get the new 3.73 gears to fit. If not I already have another plan of attack. I already have everything I need to rebuild the diff. Bearings seal and I don’t need crush washers because my diff guy is doing a crush washer elimination so it will be more...
I let my diff guy know what you said he doesn’t think it will an issue. He has done a lot of Toyota diffs and is very familiar with the 8.4. All the parts are brand new Yukon gear parts. 3.73 ring and pinion gears. Tru-trac diff.
Damn well I guess I’ll find out cause I’m about to drop parts off at my diff builders shop. How is it that urd sells a diff with 4.10’s ? Or is it that they sell it as a whole 3rd member? I believe you don’t get me wrong you have done it I have not. So if my diff builder can’t make it work what...
