Vibration in my butt with Tom Wood's shaft :)

[Dockstrada]

So I just fitted a Tom Wood DBL Cardan shaft today and I noticed a vibration only under heavy acceleration at around 60kph then it smoothens out after that.
I’m thinking I still need radial arms to re position the diff to its normal position. I'm yet to contact Tom for advice. Any ideas?

Hi Dock,

Shaft looks good. Is it a greaseless centre joint on the DC ?

Any chance of couple of close up pic's of he DC. The DC joint looks similar to joint that Cummings Truck machine shop use on my DC shaft.

Your vibration issue may disappear with Caster Correction arms, they will align the to TC and diff flanges. For 50mm lift use 3 degree arms.

I have recently fitted the TerraFirma version to achieve alignment, I was lucky enough not have any vibration issues, but I did have a Gibson DC shaft fail with only 4000k's on it.(prior to the CC arms being fitted)

Cheers

I've not long had mine, and I'm getting a little vibration around 80km/hr to 90km/hr. How big is your lift?

Sorry for the tangent... as always....

What is that service tool? Is that to grease the centre bearing?

[LowRanger]

The centre bearing on the Woods Double Cardan joint is greasable,and the tool is for doing the job.Or you can use a needle type attachment.

Hi Lowranger,

Do you know, is the DC joint a CVK2a ?

I have checked the Woods site and there is no parts listing,I have also checked the joint and there is no part number stamped on it.I just went and checked the sizes on my joint,compared to the CVK2a listed on the Hardy Spicer web site,as listed to fit Land Rover 6x6,and the sizes are different for both the centre line length and the spigot diameter.The CVK2a has a longer centre line distance ,but the woods has a larger spigot diameter.

I'm pretty sure that many of those parts are unique to Tom. He was saying to me that there was not a really good DC joint out there, the strong ones were not servicable and the servicable ones were not strong. He ended up manufacturing (or having manufactured) his own from cast steel that included the servicability so that he could have the best of both worlds with both life and strength. This is for the Rover Disco2 pattern DC joint.

It's interesting that the Bailey-Morris shafts couldn't handle sustained high speed/heat (ie. normal cruising/touring) and were pooping themselves at (I think) the centring bearing.

Was it yours that did that Drover ?

It was my bailey Morris that had the joint go in it after just 19,000km, when we went back to them they said that their shafts were only designed for low speed crawling type applications and should not be used for high speed touring. This despite their website claims as being the toughest shafts on the market.......
