I have a problem with the left rear. Im guessing the driveshaft. Vibrations, and crazy sounds when turning left.
Is there only two types? With bolt and without? And do 280s match my 450?

The 116.120 axles are the same as the 116.036 (450sel 6.9)

Are the boots tore open? If the boots are intact, it sounds like much more likely that it could be the wheel bearings. (also check the rear sway bar links)

280 and 350 use lighter duty units than the 450.

On the control note they wrote "axle damaged or deformed. Defect bearing middle axle". I guess this is what they saw. But is that the reason i only have problems on left side rear? Looks like my differential is leaking oil also.
Looks like the coupling before the middle axle bearing is deformed.

Thanks. I think i found some of the cause now.

Your pictures are of the driveshaft.  I think what your are calling a center axle.  The axles go from the differential to each rear wheel.

Your driveshaft can be rebuilt with new front, rear and center rubber and other parts.  Make sure to keep the 2 parts of the driveshaft aligned to each other exactly as they are now. use paint or a scratch to mark where there meet before you take them apart or you will need to have the entire shaft rebalanced.

Your differential looks to need a new front seal. That is a bit harder to do as the end play must be set correctly.

Yes correct. You see the bearing there. The rubber is dried up. Gonna take out the axle, replace bearing with new one, new front seal and ill change the rubber on the propshaft on each side. Guessing the vibration comes from that.
