The shift linkage isolation grommet used with type 205 and 207 transfer cases may have been sheared on some vehicles. The grommet is
usually sheared by a sharp corner on the shift lever and may result in the shift linkage becoming disengaged.
One (1) grommet is required on the K-30 linkage at the transfer case and two (2) grommets are required on the T-10 linkage, one (1) at the
transfer case and one (1) at the shifter.
Before a new grommet is installed, the bore in the lever should be inspected for burrs. The bore should be corrected with a file or stone.
The grommet should be lubricated before installation.
The grommet should be pressed into place and definitely not hammered. Hammering the grommet into place will frequently shear the
grommet.
