Bushing Correctly Installed In Caliper:

3. Unfold the bushing using your fingers or a wooden dowel until the bushing is fully seated into the caliper housing. The bushing flanges should be seated evenly on both sides of the bushing hole.
4. Lubricate the inside surfaces of the bushing using Mopar Dielectric Grease or an equivalent.

Fig 7 Installing Caliper Sleeves:

5. Install the guide pin sleeve into one end of bushing until the seal area of bushing is past the seal groove in the sleeve.
6. Holding the convoluted boot on the opposite end of the bushing, push the steel sleeve through the bushing until the bushing boot is fully seated into the seal groove on that end of sleeve. Install the other end bushing boot into the groove on that end of the bushing sleeve.

Fig 8 Installed Caliper Bushing Sleeve:

7. Verify both ends of the bushing are seated in the sleeve groves. When the sleeve is seated properly into the bushing, the sleeve/bushing can be held between your fingers and easily slid back and forth without the bushing unseating from the sleeve groove.
