I don't think this is normal ...

Put Tundra brakes on this evening and noticed the CV boots have had a jolly time spraying grease on everything behind them. I installed a 3" lift about 8 weeks ago. Was wondering if by installing the lift, changing the angle, then installing the diff drop could cause leakage in the boot seal or if there's a larger problem? Runner has 123k on it and I have all service records, never saw any CV boot or axle service. Passenger side had only a little leakage. Thanks for any help or advice -

Don't quote me on this but I believe its supposed to be easier to just change out the whole axle assembly. There's a ton of threads concerning blown cv seals though

Also, have you been doin any wheeling since your lift? If so how hard were the trails? The reason I ask is because IDK if its offroading or jst normal driving that breaks these seals. I'm planning on lifting and I do alot of highway miles and not alot of wheelin' so...

Hmm, easier to change cvs? Maybe easier to do, but replacing the boots will be easier on the wallet. You can buy a reboot kit from toyota or go the upgrade route and buy some "longer" travel cv boots as i did. And there are no seals or anything causing that leak. Just simply a torn boot from the sudden angle change.
 
Guess what, I installed a CV boot to my 4runner today. Got it from rockauto for $17 shipped. My first time replacing a CV boot and took about 2 hours. Not bad at all. If you have TOYOTA CV axles, get the boot. Special care when you are trying to clean 3 bearings... at the differential end of CV. The needles tend to fall off if you don't hold the sleeve. There is a snap ring holding this bearing unit to the CV axle shaft.

It is always fun to work on your car.

Axle nut is 35 mm, but it was so tight, I used a chisel and hammer to break it loose.....
Let me know if you need any help

A Chisel, WHAT? Wondering why?

Did it not break loose with a breaker bar? If that doesn't work break free and a cheater pipe with the breaker bar w the 35mm(if you don't have an air gun).

That's kinda what I figured. Just wanted to know if I should just go ahead and do the axles instead of just the boots since they are the originals.

Nope, no wheelin' yet, just street driving

Thanks for all the help thus far -
 
OP, please do not use a chisel! Use a breaker bar or impact wrench. Also, lock your transfer case in 4lo to prevent any movement. And personally i would go for a reboot kit. Best of luck to nissanh, but i personally wouldn't trust a $17 cv axle.

Reboot, the toyota axles are generally better than any auto store parts.

I do happen to do alot of offroading in general, but my runner is my daily driver so it does see alot of street driving. But keep in mind that even in 2wd the cv axles still rotate. So even with street driving it wears the boots down. Ive seen some people use porsche boots that work, some use oem, but those will just wear down overtime. I personally used long travel inner cv boots by offroad solutions.

Then i used long travel outer cv boots by all pro.

Thanks, man -I don't want to replace the axles unless necessary. I Appreciate the help, folks -
 
Blue,
I have a 18 inch breaker bar with a 1/2 inch driver . I tried to remove the nut while the wheel is on the ground. Had no extensions that fits the breaker bar handle, so went with the Chisel (I know it destroys the nut a bit).

Dirtwawg,
I got the boot for $17, not the entire CV axle. Rockauto have dealer closeouts and some times, you'll get things for dirt cheap.

Thanks

To answer the first question: even though you only have 120k miles, your 96 is 17 years old. That rubber is 17 years old. You should probably also replace the LBJs and radiator asap if you haven't already.

I vote you just reboot the Toyota CVs. As was already mentioned they are generally considered superior to non-Toyota.

Thanks for the advice -gonna re-boot inners and outers. Double and triple checked LBJ's and rad and both still in good condition. I do have a B &M 70268 in the truck waiting to be installed -

I highly suggest using the boots i linked above. Mine have treated me greatly. I don't have any fins on the boot touching and its made of a different type of rubber that is more forgiving.

already on it- checked them out. Gonna order both long travel inner and outers Monday. Little pricy but I'd rather do it right. Thanks for the info and the links.

How many miles do you have on your boots? what type of driving?

The 4runner I bought a month ago or so has a newly installed Toytec ultimate lift, also a freshly torn passenger side cv boot. I'm trying to decide if I want to replace the whole axles or just reboot them... I like the idea of the boots designed for more extreme angles but they aren't much less than an complete oem rebuilt unit.
 
Well i have around 3000 miles on them and they are still in perfect condition. I daily drive it with frequent offroading, about every weekend or so. They definitely see alot of suspension travel and movement. My friend has been running them on his lifted tacoma for over 20k without any problems. He recently snapped them, and he upgraded to RCV axles.

Also, just to add in, I trust my oem rebooted axles way more than i would any rebuilt or autozone axles. Mainly because i know what they have been through.
