Mercedes C Class 4Matic transfer case problem
Channel: Innovative Solutions
Date: 2016-12-23

It appears the minimal amount of parts needed to fix this problem is 2 large tapered roller bearings and one smaller tapered roller bearing. The oil seals for the output shafts on the transfer case would also be a wise decision.

Parts:
TIMKEN NP577617 (Qty. 2) - Large Roller Bearing or...
TIMKEN NP604623-90KA1 - for an assembly with the same part# above, but includes incorrect outer race.
