CV Joint Replacement

[Parso]

Update on yesterday's recovery.
Got the car back from the tracks after 3 hours and a tow / trailer. Not as bad as I thought. Can drive in Rock Crawl mode with the front left CV knocking.
My new questions are these:
Has anyone replaced these themselves? Should I do it? What else to I need to replace at the same time?

Talking to my Indy the other day and he was saying my front left cv was worn. Said it’s common on the Disco for the front left CV to fail. Sorry I can’t help, but it’s good info for others to note when it comes to preventative maintenance.

[Bulletman]

Im pretty sure Shane did a video on replacing both front CVs.

I have removed them when i replaced the front diff and pretty easy job considering, and i followed Shanes video on how to remove them.

He replaced them with repco units from memory.. check out Shanes shed on youtube and you will find it .
Also i think outback discovery did a video on how to remove the front diff that also shows how to remove the front CVs

Cheers Bulletman

I was surprised how reasonably priced a whole shaft was, at about $400. I think given mine is worn I’ll change mine out.

Easy job to replace. Support chassis on axle stand and use jack under the lower arm, remove wheel . Undo the sway bar link to top arm nut, remove tie-rod from stub axle, undo the driveshaft nut and then undo the top ball-joint to stub axle nut and pull the stub axle toward you and twist to one side and then a hard yank on the shaft and ii will come out.

[Eric SDV6SE]

As per above, only tip i can offer is to use a long flat bladed screwdriver and stick this into the gap where the shaft comes out of the differential, wedge it slightly to one side whilst giving a sharp tug on the shaft. The tip of the screwdriver should just compress the split ring that holds the shaft in the housing, the sharp tug pulls the ring over the lip in the diff.

Looked underneath mine today and noticed grease everywhere. Right front inner boot has split. FML.

Perth CV swap out party...

[DiscoJeffster]

I decided, based on the feedback from my Indy that the LH front CV was worn as is common on these, and given now the RH has split a boot, and 350,000km of use, that I’d buy two new front shafts and DIY them. Went the aftermarket path. $385 each.

Will fit them some time in the next month.

Get a 22mm socket and a breaker and get that wheel off.

Thats not broken, the wheel brace "just failed to proceed".

Definitely in “Restricted Performance” also…

[PerthDisco]

They have a safety margin of 1Nm above the specified wheel nut torque.

The trick though is to use a 6 point socket only not 12 not to destroy the nuts.

This factory tool works really well in that regard just excessively weak. Mine went same way but found another at a wrecker.

I carry a breaker bar with a socket permanently under back seats as fighting wheel nuts is such a pain in the back.

Almost there. Just can't get the cv outhttps://uploads.tapatalk-cdn.com/20240112/950e4dc96ccc098ef0ed373e4fbd38a2.jpg

Pry bar between cv and casing. Big sharp crack on the lever and the snap ring on the shaft will compress and the shaft will depart the gearbox.

[Eric SDV6SE]

Penetrant on the bash plate bolts, or cut them off and replace with new. You need a sharp angle to get the snap ring to compress. Sharp tug at the same time as you lever in, sometimes a 2 person job.

It was still super awkward with the plate off but after 4 good hits in the end of the pry bar it was out like I hadn't already been working on it for all afternoon. Time to put the car back together when the kids go to bed and put an end to this thread with some pics of the shattered CV. Thanks for playing everyone and thanks for giving me a plan @Eric SDV6SE

[DiscoJeffster]

I’ll join you in a week or so when mine turn up and I replace both on my driveway.

[Parso]

Guys. I messed up. I think the axel has fallen out while fixing out the brakes. It's now stretched the boot. Any tips for putting it back in?

The inside can fall apart in the boot and outside can’t. It fits back together just a matter of lining up the balls and grooves. Is how the unit compensates for changing length during suspension stroke. Got to be careful even during LCA change not to let it fall out.

I can't pull the whole cv out again as it's now that little bit longer

Assuming the other end was not installed back in the hub you’d just twist it a bit to allow it to pop back in to the female end near the diff. I can’t imagine it would be possible to install it popped out as you wouldn’t be able to bolt up the hub carrier with the extra length. Just by chance is it the right length did you measure it against removed one?

Should I jack up the other side or put the car into neutral to assist with spinning it?

Can you see in old one how it slots together? You want the diff end to stay still and rotate the cv shaft to locate it. Is the hub end free or installed?

Can you rotate the hub to see if it pops back in or you’ll have to fully remove the hub carrier top and bottom. Hard to imagine what’s going on without seeing it.

[Eric SDV6SE]

Are you sure that the new one is fully seated home? I haven't seen the inside of the D4 carrier where the drive shaft seats, but some FWD cars have a lip plus the split ring recess. You need to be quite forceful with it to seat them home, the ext spline on the shaft mates with the internal spline in the differential, then shove it home. Some assembly lube or gear oil on the shaft spline will help.

Have you got the shafts around the right way ? Lh for lh side, etc?

You can ,but you have to separae the upper and lower ball joints

I'm back on the road! Just became a two man job to jiggle it back in!
I'm down some steering fluid but otherwise it drove out my driveway in High Range with no big clunks!

[Parso]

For those asking about the offending cv. The outer was trashed with ball bearings dropped. The inner I wrecked the boot getting outhttps://uploads.tapatalk-cdn.com/20240113/0150515673c7d5c51aacb3784adecccb.jpg

[DiscoJeffster]

Well today I went through the process of changing my two drive shafts. I probably should have read the manual or watched a video first (Eg Shane’s wonderful video), but alas I didn’t. This led me to fighting to undo the bottom ball joint when that helped me none. Top one undone, more luck.

Found a split tie rod end boot on the drivers side so will have to fix that.

Anyhow, got the drive shafts changed and some new brake discs at the same time. The old shafts had a noticeable amount of play on the inner joints on both sides.

And as per the OP, the left hand cv was stuck fast. I really didn’t want to release, but got lucky in the end.
