Now the photo decides to load! That's how they are at the moment. The white lines were already marked on them previously and I've matched them up.

Looking at it now I probably should have flipped the top one around the other way.

If they are in the spots as you marked them all I would do is level out wieght # 2 and go from there. It's possible it may still need a balance

Did you put the donut on the gearbox in the same spot ?

What condition is it in ?

I'll straighten out that weight tomorrow and I'll see how she goes.

I slid the shaft out of the gearbox so I didn't need to touch the donut. It looks to be in good condition though with no cracks or anything.

I really appreciate your input boys! Keep up the troubleshooting.

My real issue is pitlane not being open on Saturdays. I wouldn't be in this pickle if I didn't have to take a day off work to get her down to a real mechanic. C'mon mick! Haha

And here's a photo of the new bearing and uni for those interested.

Spot any faults there?

It appears you have reassembled exactly as it was, so any imbalance must be in the new components.

If I was you I would be adjusting the position of the weight so see if you can improve any vibration. SInce you did the right thing you could always move them back to the original position if all else fails.

Can't see any issues...

Maybe put the rear up on stands (wheels off the ground)

Start the car and put her in gear, jump under and loosen the centre bearing mount bolts (while the shaft is spinning)

And then do them up again, it will help true the bearing and rubber if it is distorted

I doubt it's your problem, but I was told to do the same when I put my new tailshaft in

Also... Does it vibrate at 60kph in any gear ?

Or if you don't want to loose a finger, Place the steel rule on the uni bearing cap inline with the drive shaft and measure the clearance between the rule and fron and rear shaft. It should be even if not the bearing is two low/high

Righto Ralph I'll have a fiddle tomorrow after work with a few different configurations with the weights. Might even add a bit more weight to see if it helps.

I've had them on in three different spots now and it is definitely at its smoothest in the 'original' position. I'm starting wear out the little tabs that hold them on so I might go to ford tomorrow to get a couple new ones. Mind you that might add in even more factors to the conundrum.

I'll give that a go Wilko when I pick up my car stands. Currently living at my girlfriends place and I'm missing all my car stuff! Might even grab a dial from work to see if the tailshaft is spinning true

Good call Ralph. What sort of tolerance are we talking? Is a millimeter or two out okay? Or should I grab my micrometer set from work too?

I'll test in the morning if it vibrates in all gears Wilko. Haven't tried that yet.
