Front CV joints service
By Alejandro Gabatel, for
The new front diff bracket won’t allow the front CV’s to be removed as
easily as with the stock configuration. That’s why I decided to take some time to
do a bit of maintenance on them before putting the front end together.
This is the stuff I used for doing one shaft:
In the upper row: Bucket and parts-cleaning brush, gasoline (or the
solvent of your preference) and old rags… Middle row: Cable ties (I use ties
instead of those tuna-can-like steel clamps), two new CV boots, a tube of good-
quality grease (I’m using Mobil 1 synthetic for this job), one 57x40x10 oil seal
for the inner CV bearing retainer plate and one NTN 6306ZNRC3 bearing.
Tools: side cutting pliers, needle-nose pliers, conventional mechanic’s pliers,
Vise-Grips (two are better than one as well see later on), small flathead
screwdriver, ball peen hammer (also called mechanic’s hammer), Vinyl gloves
(for washing the parts) and Latex gloves (to save time cleaning your fingernails
after work J ).
Start work by removing the boots. Guess the bloke who rebuilt my CVs
three years ago liked to keep it cheap… He used wire instead of plastic ties or
clamps:
Use the small screwdriver to pry the wire retainer/circlip out of its groove
and pull the joint out of its housing:
This is one of the reasons why I like to do this kind of work myself. I
found out -much to my surprise- that the cage was installed backwards… The
tapered portion needs to point towards the shaft (not towards the joint housing
as shown in the picture). What I can’t figure out is how this CV didn’t knock and
grind its own way to self-destruction… Well, at least I’ll get to do it right this
time…
Remove the balls and cage from the inner joint race and toss everything
in a bucket:
…After which the old grease is removed from the joint housing cavity.
This is where the Latex gloves prove to be a good investment:
Next, put on the Vinyl gloves and give those bits a good cleaning. I like to
set the parts over some newspaper after the usual scrubbing:
