Outer CV boot repair or replace the side axle?

Hi everyone,

Recently dropped my 14 535xi for alignment at dealership and later got a call from them stating, that my left front cv boot needs to be replaced. They estimated it for 900$.

I have 2 shops where I usually go for repairs:

1st. cv boot repair kit, price 635$ included labor etc.

2nd. told me that I have to replace the entire axle instead of repairing the cv boot. I haven't got the estimate yet, but would assume it's around 700$.

So 2 questions here.

1. Would you recommend to replace the entire axle?
2. Is it a good price for indy shop?

Sorry for any grammatical errors.
Please let me know.
Thank you.

Once the boot tears, grease goes out and sand goes in. If the boot's cracked but not torn, a OE boot kit might do the trick. You might as well do the other side too, because those boots are just as old and been through the same number for miles, heat, and cold.

They make "wrap around" CV boots that glue together without having to take the axle apart. They're crap.

Replacing a boot (the right way) is labor intensive and you risk finding a damaged CV joint after opening the thing up. CV joints eventually start getting play in them, especially on cars with automatic transmissions. That jolt going into gear eventually takes its toll.

If the boot's actually torn, I'd probably replace the axle. If it's just cracked and the CV's are still good, then go with the boot kit, but on both front axles.

We just bought our first xDrive. So, I'm curious. How many miles on your car?

Back in 1995, I tore a boot on a Nissan Sentra SE-R. An OE axle was $400 back then. On my next SE-R, I put on boot kits at about 90k miles before the boots tore, and the car was fine up to when the next owner (a friend) sold it at 165k miles.

Thank you @Autoputzer

I was smart enough to not check extended warranty, that I bought and it does cover axle shafts and cv joint boots. I'll call the dealer tomorrow and see, what they'll offer.

Mileage is 105k.

cv outer boot replacement help

SO why does the BMW outer boot kit contain 3 packets of grease? 2 packets of one kind and another one in a tube. Should all 3 go in the outer boot? Seems like it'll be full up with all 3.

Some help here from a mechanic would be appreciated.

I remember my Nissan boot kits having two bottles of grease... 20 years ago, one for the inner CV joint and one for the outer CV joint. The bottles should have labels on them and there should be instructions in the kit. If not, try surfing through NewTIS.info.

no labels on the grease packets and the new tis doesn't cover rebooting.

I just caught our split boot while swapping out winter tires. Got it in right away and it was only the boot, the joint was fine. That said, boot was $100, labor was $800 at dealer (whom I trust from past work and strives to keep my costs down more than seems reasonable some times). Price of doing business I guess. 110K miles.

2 of them go on inner axle boot and the 1 different one goes in the outer boot. not sure why they include grease for inner joint with outer boot kit but oh well


to OP. Im actually doing an passanger side axle on an f10 at work tomorrow. 4.5 hrs labor and a remand bmw axle total price was somewhere around 2100 bucks if i remember correctly.

The third bottle might be differential fluid. As the fog clears, I remember some flowing out of my Nissan's transaxle when I removed the shafts for the book kit installation.

There was a hole-in-the-wall shop in my town that had one mechanic. The only thing he did all day was repair driveshafts. He did all the driveshafts for almost all the dealerships in the area. I had a lift where I worked. So, I put the car up, took the shafts out and took them to the driveshaft Bubba, and he changed out the boots and regreased everything in less than 30 minutes.

Ziggy, interesting that they include both. possibly that same boot is used for either inner or outer depending on the specific model it used on. So the small tube in the attached picture is used for the outer boot? That's not much compared to when I did them on my VW Passat a couple of times. THat was relatively easy compared to this front diff.
