CV joint stuck!!

[bert]

Good luck

Morning campers ..after a restless sleep I'm back on the case. I've done CV's in the past without a problem. In theory the old joint should have come off with a few taps ...as it was, not only did I have to slice the thing almost in half but the 'spider' (see pic) was so tight on the splines that I had to cut it in half and use a hammer and chisel to get it off ... this is unusual!! The the new CV (I've checked and it is the correct item for 2015 mazda 2 automatic) should have gone on with a good 'tap' to get over the circlip and then slide on up ...no way I have even tried the puller as a 'pusher' and now it's jammed on solid

My little Makita DTW190 impact wrench can't get off ...so my only chance is a complete driveshaft. I will check tomorrow with Mazda how much a new one will be and also ring a couple of the places you guys have kindly searched and posted on here. I'll get back tomorrow with my findings ...........

Well, I would be splitting the "new" joint - in the vice not under the car - shaft off in other words. You might find the shaft is ok, and all you need is a CV?

In theory you're right but it was a brand new cv that's stuck on ... I might get the whole shaft out and have the exact same problem fitting another cv ... I've messaged the guy selling the whole shaft for a later model to see if it will fit if not I'll try the dealer...arrgh... for a price. To be fair we've had the car 7 years without a problem so don't mind some cost now

Might shpite...
You're giving up on a shaft - without knowing it's actually knacked...
What's the "brand new CV" got to do with it?

 

[Blobber]

The last one I did on the Isuzu Trooper I had to spend a bit of time with needle files going over the splines on the shaft, I think it was just the poor tolerances on the aftermarket CV joint being too tight on the shaft

 

[gerrymoore]

If I can get the 'new' cv off I would have a look at the splines and try fitting it 'loosely' without the circlip to see if it goes on easily ... but I'll need a more powerful impact gun to get it off ... may be able to hire one although Harrison Hire have disappeared from here ...

Yep. Last clutch kit I bought, the internal splines were quite badly burred, I went over them with a needle file before it would fit. That was a LUK not a cheapy, never seen that before but it clearly does happen.

Can you not angle the joint so your balls drop out and pull the spider off with a bearing puller or can you not get enough angle with the shaft in?

 

[gerrymoore]

After this I've got no balls left to drop but it's worth a try .. tomorrow.... It's Sunday I'm resting

Have you actually checked your fault is the CV joint allowing the driveshaft to turn without transmitting drive? I wouldn’t be surprised if the inner joint at the gearbox end has popped out . Worth checking?

 

[gerrymoore]

Not the inner it's the outer turning freely on the shaft... obviously I haven't got it in far enough but it's locked solid.....I can't budge it now in or out... may hire a bigger impact wrench tomorrow to get it off if I can't get the balls out.....

If it were me I'd have the shaft in the vice by now & use a breaker bar on the puller. It's going to have to come off anyway if you fit a new shaft.

I suspect the shaft splines are damaged or the shaft mushroomed, leaving the old cv hard to get off & the new one hard to fit.

 

[gerrymoore]

If so I've gone right off mushrooms let's see what happens tomorrow... if needed I'll hire a super wrench and show it who's the boss

 

[gerrymoore]

Started bright and early .... went and hired a 500 ftlbs air windy gun ... guess what .... it wouldn't budge a thou. Tried and tried no good. So with some trouble as I'm only on a jack I managed to get the whole shaft out. Off out to the workshop and in the vice. One hour later using the biggest hammer I own ... it still won't budge.... I think the 'new' cv joint is now probably as knackered as I am ..
I'll take the windy gun back tomorrow and see if they know anywhere with a very large press who can pull the #@@%£%%** thing off ......

 

[gerrymoore]

Meant to add I rang mazda and the parts guy said £489 for a new full shaft
.. they don't supply just the cv ...then he says there are none in the UK and none in Europe may possibly be able to get from Japan but may take a few months ... wanna buy a Mazda???

Whenever I encounter something that absolutely refuses to come apart despite severe encouragement from BFH, I'm always amazed at how it ends up almost falling apart after a few hits from an air hammer.
I'd try that first, if you can get access to one.

 

[gerrymoore]

What's the difference between a windy gun and an air hammer??

 

[Guineafowl]

Air hammer:

Windy gun:

 

[gerrymoore]

I can't see that being better than a 10 ton press ???
