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

Just thought I'd add some pics of the shaft and CV angles.

Jono

lift is about 40mm over all only in the front , But im starting to think that it may have already had L/R HD springs fitted by the previous owner.

So in not sure right now .

I have aprox 125mm between the bump stop and diff pad .

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)

Nah it was supplyed with a service tool so I asume it contains grease.
Pic uploded best i could do .

Have you had a balance and alignment done after all of your suspension changes?

Hey Dock,

Sorry to hear it didn't fix your vibration. In any case it will make evrything aligned, so you didn't waste your money.

Your front end is dead ringer for mine.(arms, shocks, lift)

I only got 40mm lift from my front springs due to bull bar and winch.

I would go and get a wheel alignment as your next step. I have an adjustable panard rod but I am not sure if it is required. I only have it as it much heavier duty than the stock unit.

Good luck

Nah haven’t had it balanced or any alignment done. I find it strange that they may play a part since the vibration has only shown it’s self after I fitted the CV shaft.

Is there a torque setting for the M20 nut on the rear of the arms ?
I m guessing if they are over tightened the can drag the arms back and alter the castor angle.

I did on the other hand have a small vibration at around 80kph before the CV but after fitting a 10mm spacer to the rear which went under the bottom rear coil retainer plate.

Didn't the vibration start after you changed the suspension setup hence the reason for the dc shaft? I found with mine that even a 10mm change threw everything out which is why I eventually took it to a specialist as I was constantly chasing the problem with no satisfactory result.

The reason I mentioned the balance and alignment as I found them to be so sensitive after each change.

Total 360 with me though told me there is nothing wrong with using their shafts for highway use at all....and advised that the staff member that you guys had spoken to was wrong with what he had told you...apparently advised that in not so many words is a guy that always looks on the negative and is doom and gloom but he had not provided the correct information regarding their shafts.

they advised me that they source the best materials possible for their shafts and told me to continue using the shaft touring in Australia because it shouldnt be a problem they also advised they did change their design something like 18months ago but even so of the 100's they have sold they have only had 3 shafts return with a failure yours being one of them.

I basically told them that I would keep their shaft (and the emails they know I have other emails too regarding the other info they have given) if it was like they say nothing wrong with using it, but also told them that if this shaft lets go they are going to bloody know about it!!!
