CV joint boots torn
 
My daughter has some small tears in the front CV joint boots of her 2006 3.0. Do you guys recommend replacing just the boots or doing the entire axel/joint under these circumstances? Either way, labor is expensive but those axels are, too!

how old and how many km on the axle?

sktn77a 11-05-2014 07:58 PM

2006 (8 years old), 80,000 miles. Not sure how long the tear has been there but it wasn't there at the last oil change (7500 miles ago).

If you catch a torn CV boot quickly, you can usually just repack the joint with grease and replace the boot.

Any water/dirt ingress to the CV boot will require the axle to be replaced, otherwise it will just be a matter of time until the joint starts to make noise and eventually fail.

Get a flashlight and open the 'tear' and have a look at the grease, run your finger on the inside of the boo and feel for grit. If it's a milky colour or you can see dirt/sand in the grease then it will require removal/replacement of axle....halfshaft....whatever you guys call them in the US.

Just do the boot. The DIY (30 minute cv boot change) is the way to go. Just did it a few weeks ago.

You can get the brakes, front spindle off, driveshaft out and stipped in 30 minutes?

^^^This. If you catch the "small rips" before grease starts spewing out, just repack the joint with fresh grease and re-boot it. GKN Loebro boot kits are OEM and $20 a side.

The OEM axles are very sturdy, and proper checking will give you long life. If you have a complete tear and spewing grease everywhere, I'm afraid you may need to buy a new outer joint or a complete axle assembly. Considering I don't trust the chinese made $60 axles, an OEM GKN axle will run you about $280 per side.

If you are comfortable the joint hasn't been contaminated with grit (luckily it is just before sanding/salting season...) then I would just do the boots.

I had always been afraid of this DIY, but the axles are so expensive that I decided to try it last year. Was messy but easy. There are lots of youtube videos that walk you through it.

If you have an impact wrench appropriate to get the axle nut off and a torque wrench to torque a new axle nut down, the only other special tool you need is for those special metal band clamps that hold the boots on - you can find simple ones and fancy ones... I use a Lisle 30800 for the "ear type" clamps and a Lisle 30950 for the ones you wind up.

Once the boot cracks, there are a few scenarios:

1. Minor grease leak and no dirt ingress into the CV joint:
- Disassemble the CV joint (info in forum), clean it with solvent such as mineral spirits etc. Clean all the balls well.
- Let them dry, then
- Re-pack with grease
- New rubber boot, use only GKN or BMW dealer boot.

2. Major grease leak and dirt has entered the joint:
- Sometimes you are lucky because if you catch it early w/o CV joint damage (no clunking sound during right/left turns), then do #1 above.
- If you have clicking sound during right/left turns, time for new axle.

No clicking or other sounds yet. However, for the labor charge to disassemble, clean, repack and reassemble the old CV joints, I think it would make more sense to replace them(?)
