Front axle boot

The boot is replaceable if the axle is ok.

It looks very twisted but from what I can see in the picture, that's about it. Is the boot ripped anywhere? I'm not a mechanic but I'd think that you'd just have to replace the boot if it's too stretched and floppy.

Somebody who knows this stuff will chime in soon.

The boot had tore open when it twisted,the picture hides it. It was only drove up and down the street so there shouldn’t be any dirt inside.

Just replace the boot and ride out. You'll be fine.

Just out of curiosity, where did you buy the axle? Is it a Parts Discounter axle from Ebay?

I replaced both rear axles on my Griz and I ended up with a torn boot after the first ride too - looked a lot like yours. Now I can't seem to find a boot to fit and Parts Discounter doesn't sell boots and is not willing to direct me to their vendor. I ended up ordering another axle to get up and running. The other axle is still torn apart on my bench. I have now ordered $75 worth of boots to fix a $57 axle and none of them fit.

These are axles from niche industries from amazon. They ran me about 67$ shipped. The axles seem well built other than the outer boot problem. The boots look like the oem but the material is stiffer.

I have emailed the vendor about the problem and am waiting for a response. Hoping that they stand behind the product and replace.

Before you buy a boot, determine the axle shaft or joint has not failed. I had a rear shaft break just inside the joint and learned twisting of the boot like that is from the shaft turning and the wheel not.
Try fully engaging the diff lock, and with the wheel off the ground and the bike in park, turn the wheel by hand.
The wheel may turn but the axle from the diff may not.
I did see some ice, but not enough to bind the outside end of the boot while the inside end could turn. It's difficult to pin point the cause through the computer screen
But you do get to join the club.

Yeah...that sure looks like one thing was turning and the other thing was not!

I contacted them about mine and I was required to send the axle back for evaluation. Shipping would have cost much more than a new boot.

I ordered a new OEM boot (inside joint by mistake), then picked up a new outside boot (the one I needed) at the dealer, then ordered an All Balls (despite all the negative feedback about them) just so I could have a spare axle to swap for reduced down time when the next boot tears. Now I have a parts cabinet with an axle and boots I can't use.

I have no idea what the dimensions on the front axle are, but the boots for the rear outside need to be about 4mm larger in diameter than stock Yamaha boots or known replacement boots.

Geo Metro axle boots fit. Pick up at any auto parts store.

Edit: this is for the "HD" axles they sell for the Grizzly 660. The 700 axles are different with a smaller cv joints, so I have no idea what automotive boot fits that.

Parts discounter (niche industries) offered me a replacement axle from the bad boot. Been a good experience with this vendor.

I was going to say the same with the metro boots. I've used them on the rear of my old brute force too. I'd take the original boot in to the auto parts store and compare. Automotive boot kits also tend to be like $12 instead of $25 for atv ones.

Glad everything looks good. AmericanCV is a good one to consider for aftermarket as well, they've got a buncha boot kits and sell on ebay as well as on their site.
