Hey fellas,

So the cars on the hoist,rear springs are out, rear wheels have wen removed and disc have been re secured by bolting another disc on backwards, tried replacing rear bearings, I've now got the rear lower control arms ratchet strapped at the same height they would be if the car was on the ground.

Run the car up to 100km/hr to the speed where the car gets a vibration.

I've ruled it out to vibrating from either the tailshaft or the cv's.

Will it hurt the diff if I pull the cv's out and spin it up to "100km/hr" with no axles in?

Only way I can think of proving it's not the cv's

Ok so here's a dodgy way to balance a tail shaft

Turns out no matter how many times I would have taken the shaft out and got it rebalanced I would be fighting the diff hub thingy anyway

See pic showing bore holes for balancing now see plastic counter weights in this pic long story short if I swapped diffs and placed the weights in line with the tail shaft position as b4 using witness marks. Vibration from hell comes about over 100km/hr.

Move wheels blah blah as said in prev. Post, move weights around and wind car up to 140km/hr on hoist (coz crazy carnt on a mission) until vibration is gone.

Wouldn't recommend this method to most ppl lol

Anyway I'm happy it's all fixed.

Would have been going in circles IMO if I had of sent the tailshaft away to be rebalanced, refit oh sh*t it's still there etc etc

Here's some more pics of how I set it up

im worried that I might get some vibes when I do the T56 swap....

I can help ya out with that bud providing your tailshaft is balanced.

Just curious, how far apart are the fixing bolts for your centre bearing bracket?

nooooooooooooooooo idea!

Measure it for us if ya can. Might have a tailshaft for the box.

I've learnt that ford are fuq tards and made a bunch of different tail shafts.

They even have the dif bush bolt in different places in the b series.

Trent has a complete rear cradle with t/s n box providing those bolt holes are in the right spot for the t/s

No probs, ill see if I can jump under it and measure it up tomorrow.

Front wheels on the gutter should be enuf to slide under with a tape

I just got diff replaced and have the exact same problem, so I would have to do what you did?
