Drive shafts

[Luckyone]

Snapped the blighter, just pulling out of a petrol station & there was an almighty bang (along with that sinking feeling). On the plus side I did discover the hydratrack diff does actually do something as I made it up a reasonable hill before finding some where safe to pull over. It still had a bit of pull at 30 MPH but below it really did struggle. I managed to pull away from stand still at one set of lights but couldn’t get above walking pace, that got me to the lay by ok though. It did at least have the good grace to shear inside the CV boot so the drive shaft stayed in place, or I may have stopped a bit quicker!

Anyhow got a new one ordered & the old one came out ok, but I’m just wandering if the other is likely to be on the way out also. The parts people said it’s quite common, it’s more down to fatigue than out right abuse.

Has any one else sheared one? I did a quick search but couldn’t find much.

Yes the drive shafts have a thin part just after the splines. They allways break there.

If i was you i would be canceling your order and buy some uprated raceproved ones.

I have snapped two standard ones on my road car so replaced them with uprated ones and have never had a problem. I dont believe wear would have much to do with it, there just not 100% up to the job. Goes without saying that we also use the raceproved ones on our race car.

Ah that’s interesting, I haven’t completed the order yet. I found the raceproved site but not a price do you know how much they are?
The parts people I was enquiring with said they did sell some very nice up rated ones (I don’t know who made them) but they were having lots of trouble getting the splines to match with the CV joints, they said it wasn’t the drive shafts that were the problem it was that all the cars have slightly different CV joints as they are a generic mass produced part. So there was too much play which resulted in failure. Getting matched CV joints obviously cured the problem, but then the cost was getting out of hand. So they stopped selling them. They now only sell drive standard drive shafts with new matched CV as a package.

The 2 sets i have from race proved fit both my cerbs fine. I think although they are quite expensive they will become a fit and forget item.

Yes, sorry the raceproved site only showed the drive shaft, but in that link above it shows them with matched CVs.
The standard shaft with CVs is £250 (I think with VAT) & the raceproved one is £370 inc VAT. But then I’d need two, but as you say fit & forget.

If your CV joints are ok theres no need to change them, so saves that cost if youre on a budget.

I snapped a drive shaft about 18 months ago - luckily under warranty. It was replaced with a standard one and had no probs since.

If you scroll further down the page there is a drive shaft on its own. I though trackcar could also supply these??

So you haven't had any problems with the splines not matching up / being with in tolerance then Joolz?

Yes I noticed that, thanks & TC has them listed on their own too. Did you fit yours with the new CV joints or did you go for just the shafts on there own, if so how was the fit to the original CVs?

the raceproved shafts are an interference fit into the cv joint, ive not had one yet that hasnt had to be lightly pressed in place, but if you have a worn cv spline it might be an easy fit or even have some slop. there is slop in the std fit shafts to cv joint so how you would tell if your cv spline was worn i dont know.

Nope just got the shafts from Trackcar. They fitted fine.

Ah, thanks that's very intresting. The CV joints are all fine, so if I got some raceproved shafts only & they were all a press fit to my existing CVs then I could safely assume all was well?

Thanks Mark, seems it is quite common then. Was thinking the original standard one lasted 8 years of my driving so a new one should last for a while, but now I'm being swayed!

That would be a fair assumption as i see it.

Sounds good to me, Thanks!

[Storer]

Is this a repair that the AA breakdown repair package would cover?

They would probably not pay for the upgrade though.

Ive snapped both mine over time, replaced with standard and both still holding.











But then again I do drive like a girl
