Sent the video to RCV and all is well, so they say. Hey Randy, that worked. That noise is normal. You can continue driving on them like that or rebuild them when you have down time. Regards, Christian RCV Performance Customer Support RCV Performance Products 1500 11th Avenue Rockford, IL...

They never got back to me, but no big deal. too much work for a temporary project to pursue it.

Ugh. Well, to my dismay, the broken U joint was NOT the problem. After replacing the joint, the clickety clack remains. Can only be one thing, RCV joints are toast. The fun part starts next weekend, tearing the axles apart. RCV's are known to be a huge PITA to remove and install. Let's...

Have been dealing with a clickity clack noise for about a year. It has been progressively getting worse. The noise is only there when in Hi or Lo Lock when steering is more than 1/4 turned. Everyone said it is the RCVs, "they always click when they age", hence the reason for the excessive...

Oh wow. That sucks.

Lessons learned. After a couple of hours degreasing and cleaning up the axle housing, I came to he realization the the GMT-800 axles don't have ABS sensors in the rear. SMH, the one little thing I didn't research. I have 3 GMT-800's in the driveway and a simple crawl on my back would have...

That's good news. I did reach out to Yukon, but no answer yet on a run of H3 axles. They are soooo close to a half-ton unit that I would think the cost would be minimal.

Kind of easy but it still requires a complete rebuild with new parts. The benefit of the half-ton unit is that the R&P and locker will drop right in. That'll cost $1800+ for any other axle.

One of the guys I know has 8 lug rear 6 lug front and 6 lug spare. He carries a 8 to 6 lug adapter if he gets a flat to get him off the trail. An option until I do the D60 front.

Correct, would only need to use new lug nuts if the flange holes are different. Could not find those dimensions.

My end game is a 14b, but, if $500 can buy me a year or so it's worth it. But for anyone not looking to follow Squeaky, the 1500 axle may be a key to keeping the H3 on the trail a bit longer at minimal cost. More to come, I ordered a 1500 axle to take measurements and compare to the H3.

Has anyone looked into replacing the complete rear axle with a Silverado 1500 unit? When looking for a new spare axle shaft I am finding the GM half tons are 99% the same (if I read correctly). WMS H3 is 65.5" and 1500 is 67.5" R&P are same part numbers per Yukon. Tone rings are both 55...

Ah, nice. Look forward to the install.

Was going to ask what clearance problems there are with truck-style pumps and reservoirs?

What does that bracket give you over the old?

I spend a lot of time traveling back and forth to Texas with the wife's Suburban with the baby Duramax. Man I love this engine, can only dream of what this could have been in the H3. Cruise control on 80 and getting over 21MPG and at these prices. Can't wait for the permanent move.

Santa from Rock Auto made a special delivery, last of the big ticket items needed for the swap. Engine should be done in a few weeks then need to nail down a date to start pulling out parts. Going to wait until closer to summer have a couple trips planned to the desert yet this spring.

lol, karma for sure.

Nice, projects will keep stacking up.

Happy New Year, H4O family. I am proud to show off my new grandson and newest H4O family member, Carter.
