engine and drivetrain Broken Cv Joint

[Kpeters]

Hey guys I'm having some trouble here.

 

We were trying to change the axle boots and turns out the axles were very very stuck on the cv joints. We used a hydraulic press lightly the first one came out just fine but the second one was destroyed...

 

Now these are not available by themselves but have you bumped into a similar problem before? Any suggestions?

looks like you pressed the axles out without properly supporting the inner part of the cv joint.....

 

you cannot put any pressure on the ball cage.  heating the inner cage piece with a torch, and carefull tapping with hammer on axle while supporting the inner cage gets the axle out.

 

iirc rebuilt half shafts are available from various sources.  these are also readily available from the many folks parting out cars.

Thanks mlytle was just following the Haynes manual by the book.... Just stated to make sure the weight was being placed on the very center of the axle which we did but well.... Was trying to get only the CV joint and no the whole half shafts but guess there's no alternative!

 

Just out of curiosity how would you properly support it? We placed it between 2 wooded pieces, centered it and started applying pressure on the tiny hole in the middle of the shaft.

need two halves of a pipe or something like that wrapped around the shaft slipped up under the inner piece of the cv joint.  the load can only be on the center piece and the shaft.  the balls, cage and outer cv ring should freely move during the process.  sound like the blocks you used just supported the outer casing, so all the load from the press was placed on the cage, causing the failure you have.  if you did the other side the same way, i would toss it out.  the cage is probably deformed.

 

you have to take the entire thing off the shaft to get the cage apart.

 

ps- when just changing boots, you only have to get the cv off one side of the shaft, but if you are going to change the boots, you should take both sides completely apart, clean out all the old grease and put new stuff in.

The first one I finaly found was NOS on a shelf in room that flooded. I used the cage from it to fix it and sent it all off to Precision.I have built quite a few -but with no spares and you brake what you have.SOL. Precision did a fine job not a smear of  grease on anything and painted - just flat black but painted.1 week turn around.Heavy duty boots . You cant hardley buy the boots for what it costs to send off . I have 4 boot kits from Bav leftover.I will let go.

I broke my first one- took me 3 months to find one. They are not available accept as used or abused.I found one been setting on a shelf that got wet. The Garage guy I forget - in N.J . Had 2 still might have one.Send them off Cost me 100.00 apeace . Debured - new balls - grease - boots - painted gaurenteed .Here are some shots of mine after I repainted.There are a bunch on Utube - not the one where you pull it over a funnel- that wont work on these boots. Have to remove-clean - reenstall .  Precision Cv I think did mine in N.C. or S.C. They are on utube too . There is a clip down inside thats hard to see that must come off .They have a special way they drive it off that wont brake it . Like glass guys -they bang on that stuf and flop it around . I look at it sideways and it breaks.  Good Luck

Sorry - I will get the hang of this new version yet - dont hate me-Catman

02 rear axles rarely fail so there should be plenty of good used ones out there...Just make sure you don't get one with torn boots, which may well mean dirt contamination in the CV joints, and thus premature failure.

Thanks a lot guys great info here and yeah I only supported the casing...nothing on the Haynes pointed out that I needed to support it from the inside but ofc it makes sense. Well it does now anyway...ahhh.

I purchased a set of CV joints from LaJolla Independant for the 69.

I'd like to talk with you about the boot kits.
