Hey All
Climbed under the Bedford this morning to double check the Cresta diff ratio and spotted that the rubber hoop in the centre of my two piece driveshaft is in tatters. Explains why I am suddenly getting lots of lash in the driveline ::)
Want to get your opinions on whether I need to continue running a two piece tailshaft or whether I should be looking at converting to a single piece tailshaft when we do the diff conversion. I ran a single picee tailshaft in the CF2 behind a 350 cube Chev V8 and a TH350 auto box and never had any issues.

from my understanding you will get less vibration from a 2 piece tail shaft, but a single piece tail shaft is allot stronger. standard 4 or 6 cyl. I'd stick with the 2 piece, V8 or turbo with big horsepower, single piece for sure!!!
-
if you change your diff centre you'll have to modify your drive shaft, think the commodore is a 2 piece as well.
I think murray has a one piece bedford drive shaft down there and I might have a commodore tail shaft end

Thanks Busy. I'm thinking it might be better to go one piece if its got to be modified anyway. At least then I can do away with the bearing that sits in the rubber hoop. Don't know where I'm going to find a new one of those these days anyway. I'll get Murray's thoughts on it.

Hey Gordon...This is a picture of the crappy abortion of the tailshaft in my LWB truck.

I had nothing but trouble with it from day one. I then went to 3 different tailshaft places and they all told me that the overall lenth of the shaft was to long for a one piece. I am running a holden 6 with trimatic and holden salsibury diff. Im sure if i had a v8 it wouldnt of been a problem. I had quotes of between $450-$1400. It ended up costing me $590.00. I was told to get a 2 pce VL TURBO tailshaft and then they proceeded to cut and lengthen it to suit my truck. So the centre bearing, and carrier are vl commodore but the rear one is hz. The critical thing was to get the angle from centre bearing to the diff right. Best thing i ever did was getting that fixed up. ;D ;D

i had a trimatic / banjo tailshaft on my crapvan and am now having it shortened, new uni's and the trimatic end changed to a celica 5 speed and it should be costing 300-400, oh and its 1 piece

Pitty your in UNZED my kiwi mate has a tailshaft business here in perth

Which one Clint? ;)

Hey Gordon, If you're changing you diff center then I'd go with a one piece shaft. I'm running a one piece in my LWB and haven't had any trouble with it in 20+ years. Just get it manufacture properly and well balanced and she should be good.
Haven't got your Nationals entry from yet. Hope you can make it.

Garry, my middle bearing has done a sad on me on the Jumbo, how long is your one piece shaft, I thought going one piece on a jumbo would be to long ??? but might not have a choice as a bearing for a Bedford is out I guess umless I go to a VN 2 piece unt......

Bas, I bought an original bearing with the rubber surround and the metal outer and mounting bracket from the UK for the standard van, but it wasn't cheap. Worked out to about NZ$150 with the shipping. I wouldn't do it again.

Where from, that's not to bad a price, is the bearing pressed on ??? Cheers

Bas, it was from Adrian Bailey in the UK. I've found him very reliable. Answers his emails promptly, keeps you updated and his shipping was pretty quick. His Bedford knowledge is also exceptional. His email address is adrian@roverland.eu. He has a website too. Google adrian bailey classics I think.
-
Bas, yep it presses on to the shaft. All you need to do is seperate the two in the middle by loosening the centre bolt. Best is to loosen the bolt while the shaft is still in so you can get a bit of purchase on it. I learned that the had way :) :)
