have you tried min-its for the circlip? also be carefull not to smash the bearing casing if you use a hammer, i use a rubber mallet.

To get the driveshaft into the POT JOINT it only needs a strong push - without hammering.

I check the circlips on rough ends - in some cases i grind the ends smooth so that they do not scratch. Minispares has all the circlips you need.

Hi , just pushed my drive shaft into the pot joint and then placed the shaft into the cv joint, only to find it went in a small amount ? Not as far as the photo at the start of this thread.  I didn't hammer it into the pot joint. It is on the splines, I would say about 10mm, not close to the flat circlip. Is it a case that as the car moves about it will even it's sell out or have I got something wrong.

There should be two circlips at the outer end of the driveshaft. The one nearest the end is a round section and a fairly lose fit in it's slot. The next one is a square section and is usually a fairly snug fit on the shaft (people often think it's part of the shaft). The CV joint goes onto the end of the shaft and should squeeze the first one into it's slot and go past it. The second one acts as a depth stop. Once the CV joint is all the way on the first clip should have expanded inside it and prevents the CV from coming off the shaft without a bit of force (hence the need for a mallet to install or remove them). You need to make sure that the first clip is sitting fairly central on the shaft to be sure the CV will compress it rather than jamming it against the splines and trying to cut it - I saw a tip around using a tie-wrap around it that the CV pushes past it as it slides on (obviously you then need to cut the tie-wrap off to allow the CV to go fully home).

The circlip you see there is just to stop the shaft pushing in too far, don't try to remove it. The shaft is held by a round section clip on the end of it the pops into a groove inside the CV joint. All you need to do is to shock the shaft so that this clip pops past the groove and the shaft will come out of the joint. If the joint is free of the car this is easy, you just hold the shaft and hit the joint with a hammer. In situ it's a little more fiddly but can be done, you need to be pulling on the shaft and keeping tension on it while at the same time shocking the inner part of the joint with a drift and hammer.

 

I've been trying to get my drive shafts free of the CV joints and have used the advice you gave here back in July, it seems that no matter how much hitting the joint (or hub, or even the shaft itself) with a hammer the shafts simply will not come free, exactly how much force do you think should be required? I was intending replacing the CV joints anyway so not too bothered about damaging them but I would rather keep and refurbish the hubs so don't want to be damaging them.

 

One of the pot joints on the inner side of the drive shaft was pretty tricky to get off too, the spline seemed to have got a little rusty so was somewhat stuck, I wonder if the same problem could be hindering my ability to get the shafts free of the CV joints?

Have you got the shaft out of the hub? If not then do that first (remove the hub nut and they should pretty much just pull out by hand). Then get the CV joint and the shaft all lined up straight and give the inner end of the CV joint a clonk with a mallet or hammer - as much as possible hitting it in line down the shaft towards it's outer end.

 

If you still can't do it PM me and you can bring the shafts to my workshop and I'll show you how.

Hi Iain, many thanks! I might take you up on that offer so will PM you, here's how things stand....

In hindsight I should have loosened the castle nuts much earlier in the process (i.e. when the car was still on its wheels and had plenty of weight!) as I have that to deal with too.

You most certainty should have slackened off the hub nuts first - it's not so much the weight as the brakes you need to be able to stop the things from turning. It's going to be difficult now without making marks in the brake discs. I've kept meaning to make tool to give me a big bar on the end of a plate that locates on the wheel studs - now might be the time.

 

I'll reply to your PM.

Thanks Iain, I live and learn, and if this is the only mistake I make along the way I'll be amazed have PM'd you about working out a time for your help.

 

Cheers.
