Dont think so, it is really simple concept diesel XUD9A from PSA. Precombustion with turbine and Lucas injection pump, pretty agricultural. Besides, vibration would be present on idle and while starting which is not the case.courior wrote:Does that motor have a Dual Mass Flywheel??? If it does, and its broken, then this can cause all manner of vibration!! (you said its smooth if u let it roll down a hill so might be the motor/clutch).
I can check that, will any markings outside on the axle housing or diff says that??? Or diff need to be opened? Prior, I will check original documentation/manual that came with it, perhaps it can help...Anton wrote:Does anybody know what the standard ratio is for diffs on a diesel Sammy?

I will recheck UJ play again on jack stands, it might be some play on diffs flange but no leak so far. Handbrake is on rear drums not t Case. I wasnt noticed lack of coating on spline it was quite dirty messy. However, what I noticed (might be normal?) when car is parked in gear (props locked not spinning), when I push spline area really hard sideways small play can be felt. It is really small movement..?Jordi wrote:Loose ujs can be checked just by physically wobbling them by hand, should be able to see / feel play in them.
Depending how badly worn a pinion bearing is you can wobble the flange on the diff. Is the diff leaking oil?
Presume it is handbrake on rear drums?
When you did the props had the coating be rubbed of the splines? If they have been used with out grease the coating might have been rubbed off and it creates "slop" in the joint.
to 
clubUKI will try that too but dont think is wheel bearing because when they fail You can hear it on downhill with transmission disengaged (idling).ScottieJ wrote:Check the rear wheel bearings as well, they can make some nasty and strange noises when they have failed. jack the back axle up and give them a spin and wobble, check for play and noise while spinning the wheels.
And
This is what i found, it is original user manual and service book in swedishAnton wrote:Does anybody know what the standard ratio is for diffs on a diesel Sammy?

. Here is steering, engine and transmission info. Hope this will throw some light to ratios for diff???
