L200 Transmission Shudder...

[TimberCutterDartmoor]

Recently changed the propshaft centre bearing and UJ whilst I was at it. Now notice that under load i.e. when towing the gear lever / box shakes port and starboard like hell in first gear. Any ideas?

gearbox mount on the cross member worn??

Have you tried if it does it in 4wd?was it doing that before you done the prop joint?

Not tried it in 4wd good point. It was v noisy and there was a good ol shake under the chassis pre brearing renewal but now that is better the gear lever does the hulla - didn't before no...

We got the same problem on our L200. It is bad in 3rd gear at 30 - 40 mph. And there is a slight hum at 60 in 5th but we had the prop shaft and ujs all replaced. All of the gearbox mounts were replaced as well.

Did you put the propshaft back in the same position? If not, it may be unbalanced now

try it in 4wd firts to see if it goes away in 4wd posible ur box is on its way out,

Not much choice I recall since the bearing is mounted to the chassis with two bolts that allow about 10mm left/right position so aimed for dead centre. I think it only really manifests in 1st gear as that is when the vehicle is travelling slowly; once up to speed the vibes are gone. This makes me think the prop is doing a wobbler when turning slowly and under high torque i.e. low gear and when towing. The effect is almost non-existent when unladen etc.

Sorry, I didn't explain myself very well . I meant when you bolted the u/j flange back on, did the holes line up with the same holes they were originally bolted to? In other words, as you look at the rotation of the joint, did everything go back at the same position of the clock?
