Hi All

Recently had the drivers side (UK) driveshaft shear itself in half under the rubber dampener, which Honda replaced at great expense.

I already covered this in another thread, but I did start to think about checking the passenger side. I wasn't too bothered as my dealer suggested it looked ok (however they also on a different day said they couldn't see if it was failing anyway as there's the rubber dampener in the way).

Anyway, took a look today and I was quite surprised at how bad it looked. I'm aware that there's a difference between surface rust and structural rust, but I think this looks quite sketchy.

I had considered just spraying some silicon sealant down there, but I'm now thinking I may take it to a specialist and just pay them to swap out the half shaft for another that I purchased from a breakers that looks nowhere near as bad.

Appreciate any thoughts anyone has. Thanks.

Need a material for metal. Silicone spray is not the right material. Silicome spray is great for rubber not so good for metal. Something like Naval Jelly or other chemical that can remove the loose rust then treat with a rust converter.

Can’t really comment on the drive shaft specifically (don’t think mine is like that) but I recently had my 2011 Z serviced at the dealer and on the little health check video they do noticed some mild surface corrosion in places underneath. My plan is to coat everything in ACF-50 which I was recently recommended by a relative with a classic car. They use it in marine applications so think it is worth a try. I was surprised to find the bodywork has a 12 year anti corrosion guarantee so the underside is the main concern. Don’t know where in the UK you are based but If you are near the sea then it is twice as important.

Thanks for the reply Spdbump.

I should have added - I understand that the rubber on the dampener (pictured) starts to perish and then hold water. Hence I'm more focussed (rightly or wrongly) on preventing water from getting into that bung, because apparently this really rots the shaft out. My shaft sheared inside the bung on the other side.

I have kurust which I use on other things to derust them, I can use that on the shaft. Silicon OK for the rubber would you agree?

Thanks for taking the time.

I’m a bit confused. This is a photo of my CR-Z drivers side driveshaft (UK). Can you guys confirm, that the rubber dampener in the middle is the one which causing problems and have to be removed?

Yes slide it out of the way and witness the nightmare underneath..
So I did it today and luckily wasn't that bad.

I'm so happy I checked this before rust did some serious damage. There was some surface rust under black paint but luckily nothing serious. I decided to completely remove the rubber dampener. It is a solid piece of metal.

In the end I removed rust and sprayed a few layers of direct to rust paint and will keep an eye on it.

Good job there mimier.

Quite how Honda can recall so many cars for the protective coating failing and also ignore that as per your photos and suggest that it's fine I have absolutely no idea.

Can you please report back as to (a) whether you did all this work by only removing the wheel and (b) what the car drives like with the dampener off. Assume it's the same?

Yes. I just took the wheel off, removed the clip which hold the rubber dampener and in the end cut it with angle grinder.

So far no vibrations at all ;) Because of covid restrictions I'm not able to check it on long distance motorway driving but I'm sure will be fine.

Fantastic info there Mimier, and with great photos. Never would have guessed the damper has a ring of metal embedded in the rubber. I think anyone living where they use salt on the roads should ditch these things and I'm thinking of doing it as well despite living in a sunny and dry climate with no snow.

I did some searching after this was posted in the other thread and was amazed I hadn't seen or heard of this, even asked a bunch of other Honda gearheads and they hadn't either but the search turned up many images and driveshaft shops aware of this problem.

There are some great solutions proposed here but IMO I think I'd just ditch them completely. Lots of people use the aftermarket axles on Hondas and most of them don't come with that damper.

Again great information. Hopefully saves some people from destroyed driveshafts and all the headache associated.
