Temporary CV fix, is it do-able?

[Taresk Member Find all posts View Profile Close Taresk]

Hi, I don't mind admitting I'm a little short on mechanical knowledge, but I have a problem, I've thought of a possible fix, but need to know if it will work.

My CV's are stuffed, 6 yrs of hard 4wding have taken their toll. I need to be able to use it, but it might be 2-3 months before I can spare the cash to replace my CV's (don't want to do it on credit)

The question is... can the CV's be removed and left off until I have replacements? Is anything on the diff or hub left exposed without them? or do they absolutely have to be there to seal something up?

It's not my only transportation, but I need it for it's towbar.


Any help or insights will be much appreciated

Hi Taresk,

you have no choice, they have to stay. CVs are a big expensive job to replace, dont risk it. Mine are due soon too and ive been told by my mechanic mate that your better off getting them done sooner then later as you risk damaging other components in the long run. If there were a partime 4wd kit avaliable like what is for the 100s where you could attach free wheeling hubs, the damage could be reduced for a while until your ready to get them repaired. Doing the CV replacement yourself is a mamoth effort, ive thought about it myself. But its far too big a job for me to do, get a expert for this one,

Zook.

you could remove the front drive shaft and lock the centre diff/engage 4wd high range, that would transfer all the drive to the rear wheels only. the CV's will still be turning from the rotation of the front wheels but would not have any load/stresses on them.

I've since replaced both CV's with recon's, so it's sorted now... kinda, lol, my problems are further down the drivetrain now.

Are you talking about taking the CV joints themselves off... or the CV boots?? The way I read your post is you're wanting to take the boots off until the complete repair can be done. :?

Oops... should have read the whole thread b4 posting... didn't notice you've fixed them already

That's ok lol, but yeah at the time I was referring to the entire driveshaft, not just the boots.

The short answer, or any answer for that matter is no. Pull your CV's/drive shaft out and you'll be left with a 3 inch hole either side of the diff housing and oil coming out both ends. CV's aren't overly hard to replace and I'm interested in what you paid to have them done?

Remote area/limp to safety repair:

Remove/cut off the inner side boot. Remove the shaft and outer CV from the hub leaving the inner CV cup in the diff. On the outer side the wheel hub is pressed into the bearing, however you need to put a large HT bolt and two washers through to secure it safely (say a 20 or 24mm cap screw in 8.8, 10.9 or 12.9 grade).

I paid $300 for a pair of recon Toyota shafts, and about $50 labour for my mechanic to fit them. I don't have the space to work on my car at home, so nearly everything goes to the pro's.

@MickL : Thanks for that, handy to know.

Re: Temporary CV fix, is it do-able?

MickL could you confirm that I've got this right? I've sat and wondered on a bush fix if one of the CV's went to lunch while in the middle of no where. I'm assuming that the shaft from the CV to the cup in the diff mearly pulls straight out with a good pull once the boot is removed, leaving the cup in the diff? I wasn't aware the separation was so easy.

Does the axle and nut keep the wheel bearings and hub together? and removing same cause the bearings and hub to part company? So if I read it correctly, a cap screw around 3 inches long, washers and a nylock nut through the splined hole in the hub will keep the whole show together?

Thanks

I haven't tried it (and I hope I never have too ) but it should work assuming you are carrying the tools and bolt to do the job. I'd sure try it if it saved me a $5000 tow out of the desert :wink:

Yes the inner CV comes apart that easy. The cup is held in the diff by a circlip on the spline so it'll stay put.

The wheel side CV doesn't dismantle without specialised tools so the only option would be to remove the lot (wouldn't free wheeling hubs be nice?)
On the wheel side the wheel hub is a press fit in the bearing (so it stays together after the CV is removed) but for safety a bolt through the lot is a must. You'd have to drive with the centre diff locked too and I'd suggest a much reduced speed.

Option two is to keep driving with the CV crunching away, but if it disintegrates and the shaft starts flapping around imagine the extra damage it could do!

I can't see why it wouldn't work? Thoughts?

Thoughts? Yeah I've got thoughts. I'm thinking your the man.

Lateral thinking has never been my strong point. I only pulled out one of my CV's a week ago. Sat there looking at it for ages trying to figure out a bush repair if the CV self destructed in the middle of nowhere. Figured the best option would be to leave it in and limp home with a crunchy CV. I reakon your idea would work. I'm thinking now I can pull apart the old CV/shaft that I've yet to throw out, keep the cup as a spare should a CV pear shaped. Easier to pull out the whole thing keeping it intact and then just replace the cup. No tools required other than a breaker bar and the axle nut socket which I carry anyway.

Excellent idea.

Cheap rubber boots

See the cracks?



Please just use genuine shafts & boots. They are far superior to cheap rubber replacements.
