H3 Radiator and Cv help

[derian06]

I just recently blew my radiator and popped a cv axle within the same 5 minutes. I couldn't find any definite information on aftermarket radiators or cv's. I've broken 3 of the autozone cv's, but my passenger oem is still perfect. Should I get another autozone one or an oem?

I'm running a Silla radiator off of amazon and new cardone cv's well without issue. What are the failure modes for each?

The cv broke on the outside, and i'm guessing the radiator must have cracked. I was going to grab the 100$ one off of amazon but if you've had good luck with the silla i'll get that.

 

[jphh20]

My first Silla radiator lasted a year and started to leak on the vertical seams. They replaced under warranty no questions asked and has been fine for two years. Is ride height ok for the cv angle? I have found that the angle/height on the cv provides a smoother drivetrain ride. I'm running 28" in front with rancho/day star body lift and haven't had any issue with my cardones.

I have Cardone New CV's on my Alpha and I've got a Murray Brand Radiator from Orielly's and I've got zero complaints.

 

[Ghostbuster]

I think cardone is good if you stay at the stock ride height.

But I remember some guys talking about that the aftermarket cv axles might not have as much range of movement as the oem axles.

So if I were you I'd bit the bullet and spend $260 on an oem since your other oem is doing just fine with your current suspension set up.

Or stack up on $60 cardone axles, and hope they last.

I did a diff drop a bit ago and have had problems ever since I think I just need to bite the bullet and undo it. Cv angle looks perfect but it has been terrible ever since I'll post a pic of the cv later tonight.

 

[Ghostbuster]

Yeah that angle doesn't look bad at all. Maybe something else is causing them to fail prematurely.

I'm at 23 1/4 on my Alpha and the Cardones.

Might be driving style as well. Too much skinny pedal tends to snap CVs. Also, were you fully turned to one side when the failure happened?

 

[Ghostbuster]

And you're running 37 inch tires right? Those aren't light on the drivetrain either.

Yes fully turned to one side

 

[cbetts]

Yes fully turned to one side

There you go! Being fully turned puts sharp angles in the outer CV, just like having the t-bars cranked too high. I know it can be unavoidable sometimes but should be avoided if possible.

So never fully turn to the side? I'm thinking I just have to lower the t bars more and eventually just remove the diff drop.

Sounds like V8 power and 37s at full lock stress your aftermarket cv. You might be better off with oem cv's with your setup. What does your diff drop look like? Your front drive shaft must be at a steep angle.

Lord I haven't seen that much jerry rigging since I bought a 67 Galaxy for $50 and the motor mounts had coat hangers attached.

 

[alrock]

Umm, is that side mount even tight? If that's what it looks like now, it looks like your diff is moving around which of course is not a good thing.

 

[cgalpha08]

Take out the diff drop, it'll help save your pinion angle and bearings there.

Also, the side diff mount bushings are shot, judging from those photos, time for an upgrade or OEM replacement. However your CV snapping probably came from having the wheel cranked all the way to one side or another. Anything to one extreme or the other on a vehicle will be stressed and more likely to cause issues than when its not.

 

[derian06]

Yeah I got the how-to by rick h3t and its so strange because he has had no problems what so ever and he's running his rig at a higher cv angle with bigger heavier tires.

 

[GreatDaneHummer]

Is he using OEM CV's? I think its time to cut it off and go with a solid axle. Reading all these issues has made my mine up. Saving for a SAS now.

 

[rascole]

I replaced my cracked radiator earlier this year and have the CSF aluminum and very happy with it. As for your lift, the diff drop may by too much and the bracket bushings are toast, I replaced mine with the Scorpworks version.

I don't believe so, and I wish. But being a college student now thats going to be tough.

Any modding on getting that radiator in? Also if you did it yourself was it hard? I've never replaced a radiator before.

 

[GreatDaneHummer]

It is easy to replace the radiator but it can be messy with coolant. I also did the CSF radiator but after its all said and done I wish I would of had a custom setup made from Wizard Cooling. The CSF does not mate up well with the OEM fan shroud so you get bad air movement. You can see in my pictures how I taped up around it to help.
