Replacing (or not) driveshaft circlips

Aug 12, 2004 9 Replies

Afternoon all,



I'm in need of some opinions on what to do here...



I'm going to have to replace some knackered CV joint boots on my Rover 416 (old shape, Honda engined model). On this, the CV joints are retained on the driveshafts by springy circlips, and the driveshafts themselves are held into the diff by more springy circlips.



Good old Haynes tells me that I must replace these circlips with new ones, regardless of their condition. Unfortunately, getting new ones is looking a bit tricky. The Rover dealer (well, two different dealers, actually) tell me that the circlips are only available as part of the Rover boot repair kit. However, when I got one of them to order a boot kit for me, it didn't have the circlips in it. Apparently, they'll have to get onto the supplier, and it could take a couple of months (!!) to sort out. Right...



So, I either wait ages (during which time the boots, which are looking a little perished, will probably split completely), or I just take a chance and re-use the existing circlips. I can't really see what would be wrong with re-using them, since as long as I don't actually take them off the shaft, they won't have to spring more than a slight amount as they're pressed into their grooves as the joint is removed. Most opinions I've seen so far are that it's safe to do this. However, Haynes was most insistent about renewing them (regardless of condition!), and Rover Parts Bloke sucked air through his teeth when asked about it and mumbled something about the driveshafts falling out of the box (could this happen? Doesn't look like it could, but still...)



So...what do folks on here think? Safe to reuse old circlips, or should I persevere with trying to obtain new ones...?



Cheers,



Brian.


reuse the old, I have frequently done this, never had any problems

How many people have changed a gearbox or a clutch, and not renewed the circlips? I certainly have, many times. And has any catastrophe resulted? No.

The clips are only available as part of the boot kit, right? so hands up who believes the dealers would replace the circlips when changing a gearbox. (clue- my hand isn't up)

I say just bung'em back in as long as the clips aren't distorted or anything.

As for the driveshafts falling out of the box. Well, I suppose it *could* happen. But only if something else had gone horribly wrong first. In which case it wouldn't matter anyway.

Re-use them. Unless they've rusted very thin, which is unlikely, newness is only cosmetic.

The driveshafts would have a bloody hard job to fall out of the box if they're the type where there's a long spline that pops into the diff (which if there's a circlip involved they probably are) as the whole driveshaft needs enough movement to be able to come out. Which isn't going to happen unless by some freak of nature the track rod end nuts magically loosens itself and the track rod end pops out of where it pops in to, and the bottom balljoint magically comes loose, giving the front suspension leg enough free play for the driveshaft to come out of the gearbox/diff.

So if you wanted the dealer to replace your CV joints you'd have to wait three months? If not they either (1) Have the circlips in stock so could give you a set, or (2) Wouldn't replace the clips.

Out of curiosity phone the dealer and ask when they can do the work, when they say a few days tell them they must have the circlips in stock and find out why they can't supply them to you for three months!

The message from Brian Ruth contains these words:

I never have - except when I broke one - and it's never caused me trouble.

The message from "shazzbat" contains these words:

I've never got 'em with boots - only the boot retaining clips.

Looks like the consensus is pretty clear - safe to re-use them! I can't really see how it'd break, anyway, really, even if the circlip did come adrift.

I'll see what they look like upon disassembly, and take it from there!

Thanks, all!

Brian.

When you reassemble it - put the open bit of the clip at the top - so gravity holds it in the groove and the ends can't get caught on the way in.
