    Well project is pretty close to done. So far here's all I've done. - Replaced rear end with 14-bolt, 9.5" SF, 3.42 axle. Replacement unit had less than 100k. - Re-used all my rear brake components (except p-brake, used those from new axle), kept everything intact without opening up any...

    Woo hoo! Not a drop overnight, LubeLocker worked. Also pounded flange straight in a couple spots.

    Inserting oem tranmission oil cooler lines

    I know I’m late to the party, but I did this exact thing a few months ago, and I also took off the plastic splash guard tub underneath the front engine accessories. It’s just a few bolts and gives a lot more room

    Help!!! Broken heater hose on firewall

    Just a heads up for anyone reading this and getting ready for firewall tee replacement: I am not seeing the OEM tees on RA right now. I ordered the Dorman replacements for that reason, but after reading this thread and others I found out what a bad idea that was, and found the OEMs on Amazon.

    I have the lube locker gasket on order so I’m going to try that first, but if I can’t get a good seal I’ll go that route. Looks like $80-90 for a Yukon brand. Good progress the last several days. Ran the lines for the factory-style engine oil cooler. Piece of cake with front diff out, looks...

    Purchased a 2007 Yukon XL, now to make it reliable!

    I'm going through this with my axle replacement project right now. I think your procedure is probably in my near future. There's a little hole with a rubber plug on the back of the backing plate - it's gotta be there for adjusting parking brakes, but it seems impossible to be able to do...

    @swathdiver or @5StarCustmSolutns: could either of you send me an Amazon link for the lube locker gasket? I am not finding it there or on RA. Thanks!

    Yes, I'd say go for it with LKQ Online. More info in my post #20 of this thread, but the big benefit with LKQ Online, at least for axles and carriers, is no core charge. So if you're upgrading to AXN, that's a big plus. When I tried to order from LKQ Portland, OR (20 miles from me) they...

    Got it, thanks. Hanger bracket for both p-brake cables installed now and functional in the bracket for the LCA! All the oil had drained out of mine when I got it from LKQ, so I don't know. :-) Speaking of rear diff lube, mine's leaking. I used this gasket...

    Awesome. Hot here this weekend, too, but probably not as hot. Worst time for me is late afternoon - sun dips down and shines into my west facing OH shop door. And I was working on the back of the rig this weekend..... Got the rear end installed, all went in pretty easily. I'm to the point...

    Ah yes, maybe that's how the oil was drained. I was wondering about that since it seems like the gasket was original or at least hadn't been disturbed for a long time. In any case, I looked at it much more closely tonight, but without removing the main caps. And I've decided I'm going to...

    So is removing the carrier a simple unbolt/bolt back in operation? All the shimming is done with pinion? I’ve never done anything with a diff before. There was no oil in the case when I got it, whereas first one from LKQ was full. I was thinking that part of diff just dried out over time and...

    Awesome! Glad to hear that works. I may consider that in the future. Picked up 2nd try axle today at Portland LKQ. This one much better regarding suspension attachments - all brackets are nice and straight. I was a little disappointed to see some surface rust on the diff flange where the...

    Dumb question: could you do a hummer mount on DS and stick with Tahoe OEM on Pass side? I'm not going to do this now, but something I've been thinking about if I DO have a failure on DS some day, or if I do some motor upgrades.

    Thanks but slightly different story for me with LKQ. In an earlier post, I advised others they should order from their local LKQ rather than LKQ online. I am backtracking that advice now - LKQ online is the way to go if you are doing an upgrade, e.g. 8.5 to 9.5 rear end. The reason - NO CORE...

    Well I ordered a Denso 2219514 radiator AND a single GM OEM motor mount from RA today. More projects and extending my down-time for the Tahoe by a couple weeks. While I’m there syndrome….. On the motor mount I think a GM OEM will be sufficient for my 5.3 and fairly benign driving habits. I...

    Several months/2k miles ago I did all four control arms with Delphis. Quite a bit cheaper than GM, but the castings and all the hardware looked identical. We’ll see how they last. My rig had 200k on it then, just the drivers side upper had a little play.

    Ok, here's the post where I ask what else I should do when I have both diffs out. For the back, so far it's just the evap charcoal canister. I've read too many posts here lately about those failing so I bought a GM OEM and have it now, will install this weekend. (I know it's probably not much...

    Thanks for all your thoughts and advice. I've already started the return with LKQ for the rear end. If it were just the track bar bracket and the control arm bracket I would probably straighten as best I can, but then later I discovered that the PS flange where the dust shields/p-brake mount...

    Whew, I ordered 51350X (5-1350X) from RA. (Actually ordered two, might as well do the other one on the rear driveshaft as well.) I've been nervous all day, after I read your first post about 1350 vs 1355. I wasn't sure which one I ordered (just used RA's part selector tool) and didn't know...

    Thanks for the info. I found more damage tonight - the flange that the brake backing plate/parking brake mounts to is bent on one corner. That seals the deal, I'm going to start my return/exchange with LKQ tomorrow and hope my second attempt is more successful. I'll do a lot more close...

    Thanks for the encouragement to make some "adjustments," James. I did use a long 2x4 to try and lever the upper bracket back into place, along with several well-placed blows with a 2lb machinist hammer. It's better now, but I think it's still going to be challenging to get the upper arm/strut...

    I have a local tuner I use. I've already had ECM and TCM tuned from him, so I was planning on just going back to him and have the gear ratio changed in the tune. He used a pretty standard upgrade for shift schedule previously, and I like the current shift points, RPM-wise. I was thinking I...
