cv axle boots replace or buy new axle?
Hello, I have a 85 nissan sentra that has 140, 000 on it. I noticed that the axle boots have a crack all the way around them. They are not leaking grease yet, but I would like to know the pros and cons of replacing the boots or just buying the reman axle. I think axles are $65 an axle. Thats more than 2 boots at 10 bucks each. I just hate to put this thing back together not done right, but not looking forward to spending 130 for new axles either. I was told that the outer joints do not come off, and I would have to remove the inner joint to get the outer boot off. Are these things a royal pain to do. I really dont have a parts washer to clean them out properly, so I guess it would be boat loads of carb or parts cleaner cans to clean these joints. As far as I know there is no easy way to clean these either.

No man, you can get boots that are split in half. they use small bolts to clamp the boot together.

Believe me...
Replacement shafts at 65.00 a piece is a bargain. It saves breaking the CV joint down, cleaning...inspection, reassembling and putting the boot on.

I agree with KULTULZ.
I've changed tons of cv joints way back before the reman units came out. If you know how to do it, changing boots is not hard,,,,,,,BUT, with that many miles, and the fact that the boots are already opened up, i'd change both shafts and call it good. Once some dirt or dust gets into the joints, they wear real fast. You can save some bucks and re-boot them, but it may be just a temporary fix. Mark

If I could get those axles for that price, I wouldn't even think of trying to fix the original ones.

Uh guys, you can get repair boots that are split. you don't have to
take the axals off the car to install them either. they just wrap around were the old ones are.

If the boots are split, the CV joints are contaminated and will shortly be toast IMO. I would replace the shafts, especially at $65 a piece.

Wait
Sounds like you pay attention to your car. Lots of people dont. I would continue to drive it for awhile. Pay attention to sounds and feel. You should be able to get through a couple of months as is. Take the time to collect the money and do the complete job. Depending on how hard you drive and how many miles, you might even get six months to spread it over. UPSIDE you get time to get money. DOWNSIDE - none.

  Now about the question. There are many of us in the field who would rather rebuild the original shafts correctly than use reman shafts. This is mostly due to the fact that unfortunately the quality of many of these reman shafts is less than terrific. Considering though that you are doing the job yourself, do not have a parts cleaning tank and all the tools that a full-time mechanic would have, and are not experienced with disassembling these shafts, I would have to agree with KULTULZ and others and say use reman shafts. The one redeeming quality they have is that usually they come with a good warranty, sometimes lifetime warranty. Easier on your part and if they fail you can pull them out yourself and get them replaced under warranty.

Hey it's a cheap fix, not that I would use them. And the other dude is right, you can drive a long time with bad boots. And even if they have split the grit can be cleaned out.

1. Most of us that have been around for a while try to never recommend a 'fix' that we would not do or have not done ourselves. 2. Most people drive around for months before realizing their CV boots are ripped. The most common sign that the CV joints themselves are in serious condition is a repeated clicking sound on sharp left or right turns. When this happens it is definately time to fix them or risk complete joint failure.

I have seen numerous times that people have tried the split boots. I have not seen anyone that has been successfull with them. The boots need to be glued closed. That is extremely difficult when it is full of grease, as glue usually don't work in grease. Simply replacing the boot does not correct the problem, as there is now grease missing and most likely dirt in the joint. The best bet is to go ahead and replace the axle if you can get it at that price.

I've never used them, but the guy wanted a quick fix so... And it's either that or replacing the axal, the boots are way too hard to replace.

ISSUE
The real issue is not if the boot will seal or not. The real issue is the fact that once broken open the area becomes contaminated with road debris. The best fix is a removal / clean / reassemble. Some of us work our ...... off and can not afford THE PROPER WAY. So we look for ideas / advice to get us through. Replacing the boots will slow down the contamination but is not the END ALL answer. And the reason I am broke is not the amount of drugs I am taking or how small my welfare check is.
hr41pearl OH, the real reason I am broke is this hot rod I am working on.
