Membership of the wheel tappers and shunters club that is!
Some seem to be moving over to the key tappers and paper shufflers GRRr, trying to keep their Lilly whites (hands) clean!
I am seeing large propensity of Sprinter rolling into the shop with LOOSE REAR AXLES and wallowed out spring perches with damaged rear springs in many cases.
This can be easily be detected in its early days and remedied if you would get back into the wheel tappers club (its free) and check the U bolts with hammer and shunt some new U bolts under there when needed.
Just simply tap the U bolt with a hammer!
If its tight it will ping!
If its loose it will make a thunk sound.

If its rusted in place it MUST be freed off and re-torqued !Taken directly from WIS this morning the torque U-bolts as follows
[B]SPRING U- bolt on rear axle spring to rear axle M14X1.5 Nm 160 Model 906.6/7[/B]
[B]Rear spring U-Bolt to rear axle m14X1.5 Model 904./5 690.612/613.904 Nm 170[/B]
So:
NVC3 - 118 foot lbs torque for the 2007 and up Sprinters and
T1N - 125 ft/lbs for the 904 or 2001-2006 Sprinters.
Hope that helps a bit.
