CV boot installation, 74, 911
 

Hi Guys,
I'm having trouble stretching the boot over the CV flange, tried Snap ON hook, grease, strong language and a heat gun, but the mf's will not go over the flange.
I have the axles, boots and CV's lubed, clocked and installed, on the bench, but lack the wit to get the boots on the CV flanges.

HELP,
chris

in retrospect...
 

Looks like it would have been easier to install the boots on the flanges BEFORE sliding the small end over the shaft !!!


But hell, there're clocked, installed and lubed - backing up is painful.

I'll bump this for one more try, before i press off the lubed CV to get the boot on the metal flange.

Any advice on stretching the boot onto the flange??? Or, should i have put the boot on the flange before installing it on the axle???

Sometimes timing is everything---

I just did this (I think). Drivers inboard boot ripped. Just wanted to replace boot so I dropped the inboard CV, disassembled, removed old boot, packed grease and put new boot on axle. I bolted back up relatively snug then got into a mofo of a wrestling match with my arms above my head getting that boot on the flange. Feel your pain. Harness your caveman and walk away as needed.

Over in our 911 tech articles section I found one for the CV joints:

In the questions section towards the bottom somebody had a similar issue. The response was:

Hi Old,
So, what combination of "tools" enabled you to get the boot on without tearing the rubber??
Matt, Nick's reply was to a question i posed about this problem, he misunderstood my delima, the boots are on the assembled shaft, i just can't get them stretched over the flange of the tin shield.

I've done a few and have never had this issue.

My guess is wrong boots or bad boots or tin.

edit: could be your tins are all bent out from mishandling, usually I have to massage them with a hammer to get them round again.
How about a picture?

Hey Chris,

Used a plastic lever tool typically used for upholstery or more delicate stuff. It’s from a variety pack I buy at HF for like $2. I used it to lever the boot onto the flange. Then rotate while continuing to pry. Again, this was on 930 CVs.
