Blown CV Boots on my 2000 tacoma w/fabtech 3.5" coilovers
 

I have a 2000 toyota tacoma ext cab V6 with a fabtech 3.5" coilover lift and 32" tires. My problem is that I blew out my inner cv boots on the driver and passenger side. I just had the passenger side boot and axle replaced by toyota about 2 months ago. I thought that it was just a bad boot the first time, but now I'm suspecting the lift. I don't understand why this is happening on this truck because I had this same lift on my 98 tacoma 4cyl reg cab with no problems. Has anybody ran into this problem?

Do you have a diff drop kit?

That's about max lift height before people start having a lot of problems.

Do you have any tools? Changing out a boot is not that hard once you do it.

I don't have a diff drop kit, but I do have access to tools. I'm not too worried about changing them out as much as trying to figure out why it keeps doing this.
Thanks for the help.

because of the extreme angle the ribs of the boot rub together, which wears them out. At stock height the rubber isnt in contact. diff drop returns your angle to near stock and should greatly extend the life of the boots, or you could install manual hubs, which prevents the front driveline from turning on the street but is $$$ for your generation truck

With the lift, the boot is stretched to the limit, causing the boot to leak or even tear, I recently helped charles replace his boots with a pair used on the VW 930 CV's. You need to cut a portion of the stock boot to use as a seal, but they will allow more flex and should hold up quite well. I've had them on my modified Tundra axles and have had no problems. They are a bit pricey but worth it. I got mine from Kartek....

That makes sense because my 98' had manual hubs. So I guess I need to get a diff drop kit. Any suggestions on good ones?
Thanks alot. This will definitly help me.
Thanks again for the help.

You can make your own, or purchase a kit from a number of guys here on Yotatech. Do a search for "diff drop" and see what you come up with. Remember, this will only help a little. The ultimate fix is a better boot design (for extreme angles), manual hub conversion, or "lowering" your rig a bit.

Lots of great info on here. Keep looking around.

id reccommend roger brown's kit. hes a good guy

I too have the Fabtech lift on my Taco. I have not had any problems as of yet but I have a diff drop kit installed on mine.

I would suggest purchasing one right away or continue to replace cv boots.

How high do you have your lift set in the front? With 32" tires you shouldn't need 3.5" and with automatic hubs the highest recommended lift is 2.5" with the coilovers in the front.

I'm curious also as to how much lift you have it set at.

not only is the boot rubbing and stretching etc., the halfshaft is also probably rubbing the inside of the baffles, if your setup is similar to mine. diff drop spacers, 930 boots, and turn that sucker down to 2.5" or 3" or so...or get your wallet ready for a manual hub conversion. it's 450 to a grand for a conversion for a late model, plus installation time and/or money.

bluntly, youre tearing boots because your lift is cranked too high.
