CV Axel Rubber keeps cracking - Toyota 4Runner Forum

meltdowner · 10-17-2021, 12:56 PM

I went through two CV axel's in the past 1-2 years. One only lasted a year before the grease starting spraying out of the boot. Is this a common issue? Anyone know what can be done to fix these crapping "rubber" boots that are filled with grease?

Are you using aftermarket axels or OEM?

I have remanned OEM's with Toyota boots from CVJ that I installed 6 years ago and they are in perfect shape still with over 100,000 miles on them.

Are the ribs rubbing when driving in a straight line? Or is it from UV degradation? If the ribs are rubbing eachother you could massage the boot a little or extend the clamp possibly.

With the vehicle sitting on level ground, get under there and look at the axle angle at the inboard joint leaving the differential. Sagging suspension will have the axles angled upward significantly where they leave the tulip joint, causing the inboard rubber boot to rub against itself. The friction and abrasive dirt will cause the boot to fail more quickly than one operated at normal geometry, with spacing between the boot bellows.

If you have any notable lift, the bellows can touch.

It's a more common problem on 3rd gens, this is a pretty good thread that talks about what to see and what to do:
Stretch your CV boots

Hope that helps.

Another thing to add. When you part your car for the day make sure your wheels are straight. Less stress on the boots.

My dealer will only sell a complete inner and outer boot set and i think he said 170 bucks. I just need the outside one.

Is there a better brand of aftermarket boot?

I have a spare brand new outboard boot (thermoplastic) I didn't use from my kit, PM me a reasonable offer and it's yours.

Here's the Toyota boot kit including both inboard and outboard boots, grease, and clamps at $48:

or either take the dive on new CVJ's or get CVJ replacement boots.

OEM boots will last far, far longer than a year. Aftermarket? Who knows... A boot kit from the parts counter should NOT be over 100, not even over 50. I think my kit was about 30.

OEM or gtfo

The part number you posted is an old part number that has been superseded have you tried to get the parts using an updated part number, the part number in the post you quoted is the correct up to date part number , which is..... Boot Kit - Toyota (04427-60141), just an FYI the old part number you posted is missing a number the first 5 numbers should be 04438, what you posted is missing the 0 as the first number.

Yeah my OEM boots are in perfect condition after 100,000. The inner joint went out before those boots.

You might find some bad OEMs with good boots.
