Most CVs won't like the new angle after being at the original angle for so many years. Most likely they will start throwing grease right away and fail later on down the road. I ran mine with basically no grease in them and torn boots (which I duct-taped) for a full year and finally replaced them because I was doing my ball joints anyways and it was a convenient time to do it. They never did break though. I know a guy who has a 2nd gen and his CVs have had torn boots for 3 years and no popping yet.
You could try putting some hose clamps on the boots to prevent leaking grease, but make sure the clamps don't tear into the rubber when it spins. If I was you, I would hold off and see how they do because some people don't have problems. I definitely suggest a diff drop though and install it at the same time as the lift.
what is involved with changing the boots. im thinking of doing those neoprene boots. someone on here has them
Thanks for your reply Brian. Here's the thing. I'm in college right now and I live 100 miles from the garage that i use (thanks mum and dad!!). So I'll drive up to their place to install the lift and then drive back to school. I don't want to be doing repairs in the parking lot while I'm here at school. I'm just worried I'm going to get back here and the boots will be torn or leaking and I'm stuck. do you think I could get away with duck taping them for the drive back to my parents house?
Check this out. It doesn't look too bad: http://www.toyota-4runner.org/maintenance/37107-front-lh-inner-cv-boot-leaking.html
my rig has 231,000 on it..As soon as i did my lift mine started throwing grease as soon as i drove it. I cant find any rips in the boots at all...So i will run them till i hear popping....It is what it is....
I have nothing of real value to add other than my CVs on my 2nd gen have been blown and popping for 6 years and the effer just keeps going.
