Cv boot replacement

I had a stick tear a rear boot today. Need to get it fixed before a big memorial weekend ride. Are these things replaceable? I had to ride about 25 miles after so the joint may be junk anyways.

I'm leaning towards the super atv rhino axles. Their super quick shipping will get them to me Tuesday or Wednesday, but I'm hoping I can just get a boot at the dealer tomorrow.

Probably the joint is still OK if cleaned out and re-lubed and a new boot installed right away. It takes time and grit to destroy the joint.

So there was a fair amount of grit in the grease and joint. The cv pops right off the axle with a rubber mallet so changing the boot is easy. I'm soaking it now. It feels tight but I can feel a little grit in it when moving it around.

I assume the new boot comes with grease but if not does it require a special grease?

I'd find a shop with a solvent bath with a pump and clean it under the running fluid until all the grit washes out. I think any hi-pressure grease should work. Most boot kits I've seen come with a packet of grease. Autozone includes a 3 ounce packet of grease with a boot kit.

Generic grease and clamps are available at Autozone.

Omg, same thing happened to me, just two days ago! A Fricken Stick poked right through the rear inner boot...:cussing:
Anyhow, I got the boot slipped back on, and I am hoping to ride this weekend also, I guess I am staying out of the mud puddles. only 234 miles on it. I'm furious.

I'll be buying A-arm skid plates instead.

On my second ride, less than 10 miles on my RZR. I noticed a small hole in the driver's side front inner boot. Looked like a stick at poked it. Just alittle grease at the hole so I bought a inner tube patch kit. Cleaned the boot good and followed the directions from the kit and placed a patch on the hole. Over 400 miles later the patch is good shape. I now carry the kit with me on rides just in case I get another hole.

I hate to revive an old thread but I just tore a rear inboard boot. Did the slip on boot work well for you? I do not want to take the axle out of the cv joint unless I have to. Also I'm assuming they sell the universal ones at a parts store correct? Sorry for the questions. Not a mechanic. Just enough to get by.

If I had to do it all over again I would have definitely gotten a boot kitkit cone to slip boot on because slipping the boot over the axle is very difficult. All Balls racing sells specific boots for the 900s, and the whole kit was 19.99. I used heavy black wire ties instead of the cheap metal clamps that came with the kit. Been a while now and all is good again. Good luck

Ok when it comes to CV grease, I'll let you guys in on a secret. I've been involved in off road desert racing most of my life. I've won Score races & BITD Championships. I've been in everything from Class 1 Unlimited Buggy's, to 5/1600 Baja Bugs.

When it comes to CV grease we use Bel Ray. (Bel-Ray 67700 Molylube Anti-Seize Compound, Grade NLGI 2). It comes in 14oz cocking tubes. The cocking tubes are Awesome! Super easy to pump grease in without using your hands or sticks. I would guess one tube should do two compete UTV axles (4 CV's as UTV CV's are pretty small) This stuff is not cheap! It's around $45 per tube. But it's the best! It's the norm in desert racing and I would bet the Polaris JaggedX and other top teams are using Bel Ray. Bel Ray is rated up to 750 degrees Fahrenheit. We have had 1000's of miles on 930 race CV's and they show very little wear.

On the Class 1 car we have lost CV boots and continued to race with only pumping in more grease at pit stops. Bel Ray is a Moly Paste with Anti Seize and this is what makes it so good. This is what will stain your hands too! Bel Ray is thick and does not liquefy even at extreme high temps. This is what keeps it in the CV and not in the boot.

We have learned many boots rip as the grease melts and is flung into the boot. The centrifugal force causes the boot the rotate and deform out of shape with the grease in the boot causing them to rip.

I worked with Huskey Lubricants to develop a better CV grease back in 2003. What they came up with was a combo of their Moly & anti-seize grease. Basically what Bel Ray was making. A limited production was made and tested. It worked great, but the higher ups pulled the plug as it was going to be a specialty grease and they felt is was not going to be cost effective to mass produce.

If Bel Ray is to costly for you look at Caterpillar Grease ( Cat Gold ). This is much cheaper and works very well on limited HP cars, which the UTV would be in that category. Many limited class teams us it with great success. I have used Cat Gold in the Prerunners. But if you want the best look at Bel Ray.

Now the secret is out. Keep using your PepBoys cheap universal grease and keep having issues, or look to the best.

Good advice! I work on so many vehicles, always seems only the brand new cv half shaft gets a hole in the boot... the slip on boots have saved the day!!
I have also tried to use silicoln to patch small holes, it does not hold. The innner tube patch kit idea is great thanks for that.

No they do not sell stretch style cv boots at the auto parts store, not yet. They still sell the crappy split boot style ones, where the new boot is slit all the way down and it relys on clamps just to hold it on...temp fix for sure.

Slip on boots are the shizznizzzle..... cut old one off, use cone and grease, slide new one on...saves so much $$$ in cv axle replacements!! I always have one of the small ones on my shelf ready to fix any rzr that gets a ripped boot
