HELP!! Repeated Inner CV Boot Tears!!
 

Hi Guys-

I recently put new tires, shocks/struts, brakes, callipers, lower ball joints, axle seal on my 06 H3/85K. It has a 3 inch lift. After putting the tires on I took it and got it aligned. I noticed the one inner boot was torn when they had it on the, lift. After taking a better look both of the front were torn. Fast forward 20 miles later, completely thrashed.

So I replaced them on Friday, drove it around town for about 20 miles checked no problem no clicking. Took it to see family today about 40 miles round trip and the new set is completely thrashed. Grease every where!

Any ideas?

Should I call it quits with the hummer or try to replace again?

HELP!

I'm guessing you maxed out the CV's.
Boots are failing because of excessive angle?
Boots are failing because of touching?

seems like there was a thread about lowering the front diff. it went on and on..lots of differing opinions there!!

leave me out, just saying,,,

What 3" lift?

I think Happy Hummer nailed it after really thinking about it. The fins might be touching from the angle. I stopped at the garage I usually have work done that I don't want to do and they suggest getting some OEM boots and replacing the cracked ones. And also threw out the idea of RCV axles if they made them. I don't have deep pockets for that right now, but I did call them and suggested these

Going to give these a try. Has anyone tried them before? The gentleman on phone said they are stronger than OEM and allow for an additional 10 degrees of max angle.

If these do not work anyone have any solutions that have worked for them?

Please answer Doc's question about what lift you are using to get the 3" increase.
Is it a true lift or just a leveling kit?

Putting on new boots is just a bandaid.
We need more information, like measurement from the center of the front hub to the underside if the fender to get an idea about what you are dealing with.

Here is what I found after doing some digging. I replaced the suspension with Pro Comp ES9000s on front and rears. Lifted with a 2+ inch rear shackle and 3+ front Torsion Keys.

center of hub to underside is 26 3/4 inches on both sides in the front. Running 35 inch tires.

Easy answer, you are way over max height in the front. Factory keys get you the same max = 23.5-6". Go beyond that, even with your aftermarket keys, you are tearing up the front, nobody's CV boots will take that punishment.

26 3/4"? I think you made a mistake in measuring. Anything past 24" usually self destructs when wheeling in short order.

So I need to bring the front down close to 24 inches then correct? I am also assuming I can keep the after market keys on as well?

Six years ago or so the general consensus of the H3 off road community was that 24" was the max. After a few years of wheeling like that it became apparent that even 24" was too much as guys were tearing up half shafts, CV boots, front diffs, and half shafts would pop out from the inner end destroying the shaft splines. Street Queens might be able to get away with that for a while longer.

23.5 -23.6" is about as much as you can go without breaking your stuff.

Your aftermarket keys can stay in, if they will allow you to back out the T Bar bolt to the lower position and still have thread through the Keys.

Almost forgot, you will need an alignment after the adjustment.

Jimy, read this, It explains a lot regarding the H3 front end: https://www.hummerforums.com/forum/h...ics-how-11428/

Thanks guys. I had read on another forum that people were able to 27.... however 24 seems like a very real solution. I am going to start working on this Friday and will see how it goes. Any other suggestions? Since I am familiar with removing/installing the axles should be a little quicker this time lol.

That would be with a real lift kit, like a Rancho that lowers the front diff. while lifting the truck. You're never going to get there with Keys, spacers and shackles.
