anyone running these?

 

[Mb30sdl]

Yes, but mine are in dayna 60.

I wouldn't run them...CVs aren't the issue. Most people break the diff before breaking the stock CVs

 

[Mb30sdl]

I think it's backwards CV (stock) breakes before diff. So it is sort of cheap insurance

 

[Vdawg1115]

What about us boys with Cast Iron front diffs? I would imagine it would work

 

[RamRod]

I have broke 4 CV's.... zero front diffs (knock on wood)

I am going to order some RCV's once I break one more CV..... I have a spare to go in while the parts are on their way and getting swapped onto OEM half shafts

 

[Vdawg1115]

I thought it was weird that they only offer a outer half CV shaft. They normally do a full IFS CV shaft.....well, those are $2500 for a pair though. Are the stock H3 inner shafts pretty strong? Is it only the out that normally break?

 

[RamRod]

In my experience it's the CV joint that fails not the OEM shaft... not that it wouldn't break under certain circumstances

Nope, that's theory but not reality. More broken front diffs then CVs on this forum for H3s

 

[cgalpha08]

These are just the joint, IIRC its the actual shaft between the joints that snaps, if i'm remembering the pictures correctly. (don't hold this against me if im wrong lol)

 

[jakesz28]

I would rather change a CV on the trail and continue on my way than move the weak spot to the front differential.

 

[Best4x4]

If you swap out the CV's to the RCV's the possibility of breaking something moves up the chain. In an H3's case the front diff.... I've got a CI front diff on my Alpha, but I'd rather break a CV vs front diff any day!!!

I used to so laugh at people in Jeep's especially with a rear Dana 35 axle. They'd break a rear drive shaft, upgrade the rear drive shaft, then twist a rear axle shaft, then they'd beef up the axle shafts only to blow the gears out after that. With the time & $$$$ they spent on all of that they could have dropped in a Dana 44 or 60..... Point is if you beef up one part, the weak link will just move down to the next part...

It doesn't matter...the whole thing is junk. If RCV can make money by putting lipstick on a pig...then so be it. FWIW...I smoked (3) AAM-7s and still had original GM half-shafts.

 

[cbetts]

I can't justify the cost. The only time I broke a CV was mainly because I was running a cheap Chinese SurTrack. If everything else on the truck was beefy, maybe I would invest in the RCVs.

 

[Mb30sdl]

The reality is it has more movement vs. u-joint(plus better power transfer - not bind up at full lock) so I used it in SAS swap in H2 to get better turning radius and it is notisable compear to H3 with u-joints.

 

[amrg]

My CV joints lasted 100K miles, offroaded my truck every sunday!
So RCVs are probably overkill...

I'm agreeing with for 4-speed on this point. Both the CVs and the diff are weak points. My opinion you eat there learn to live with it or replace the whole thing. Right now for me it's better just to live with it and replace parts as needed

Let me add that were beginning to get a history now on aftermarket CVs. That history is showing that the OEM ones are much better than the Cardones. Yet I will still be running Cardones for a while

The H3 doesn't use u joints on ifs. Rcv has its area of needs for solid axles but on a front diff that is a ticking time bomb it doesn't matter

 

[Mb30sdl]

I know IFS doesn't use U-joints. Alter grenadine one on H2 and one on H3 it was time to upgrade. And so far no one seem to grenade front diff. Before CV.

 

[derian06]

98k on the driver side original
10miles on the next one
On my third one

 

[06 H3]

4 front diffs zero CVs for me
Bebe 3 front diffs zero CVs
4speed 3 front diffs Zero CVs
08 H3 I believe had a front diff go with no CV issues

 

[Best4x4]

I've had excellent luck with my new Cardone CV's (Not the refurb units). Only issue I had after first installing them was leaking axle seals. After further investigation the "National Oil" branded Axle seals were the problem and not the Cardone CV's. Installed some AC Delco Axle seals and I've been good to go for nearly 15K. I also remember grabbing them off Rock Auto for just 50.00, and now their 75.00. I think the Empire or EMPI branded ones were failing more vs Cardone's.

 

[High Five H2]

I just broke my 3rd CV shaft, but never broke a diff. I'd rather change a CV than a differential any day. I wouldn't bother with RCV shafts, especially since my most recent shaft broke on the inner CV, not the outer one that this one replaces.

 

[06 H3]

For guys that break CVs this could be a good upgrade. for guys who break diffs before CVs then it doesn't matter what CV they are running
