Condition
Some customers may comment on a red fluid leak from the transmission or transfer case area. Technicians may find that the fluid is leaking from the
transfer case/PTU weep hole farthest from the transmission, near the passenger side.
Cause
The front wheel drive intermediate (inner) shaft seal may be leaking. Due to low ambient temperatures with various runout conditions between the
intermediate drive shaft and the input shaft, the seal material may not properly seal automatic transmission fluid (ATF).
Correction
Replace the front wheel drive intermediate (inner) shaft seal with a new designed seal.
Important
Selecting the correct replacement seal is critical due to a 2008 mid-model design update. Use the information below to determine which seal to
use. For additional information, refer to New Product Information in the Getrag 760/790 Transfer Case category in SI.
