Drive/Propeller Shaft: All Technical Service Bulletins
Propeller Shaft CV Joint Boot - Leaks Grease
NUMBER: 93-T-69
CORP.REF.NO: 264101
DATE: June 1993
SECTION: 4A
SUBJECT:
GREASE LEAK - REPLACE PROPELLER SHAFT
MODELS/YEARS:
1991-93 BRAVADA
CONDITION:
Some 1991-93 Bravadas may exhibit a grease leak at the front propeller shaft constant velocity joint boot. Owners may not notice this condition until a
grease spot appears under the vehicle or when the vehicle is serviced for routine maintenance.
CAUSE:
One cause for the boot tear is that the constant velocity joint boot was produced with an oversized diameter. The boot retainer clamp has a reduced
diameter design. The combination of the oversize boot and under-size retainer clamp, along with the twisting action of normal driving, could produce a
tear. Another cause may be an outer boot retainer ring dislodging from the inner constant velocity "can".
CORRECTION:
To correct this condition, a complete propeller shaft replacement is required. The front propeller shaft is a system balanced assembly which is matched to
the front differential. It is not necessary to replace the front differential assembly as part of the original "matched set". Be sure to carefully match the
alignment marks on the propeller shaft flange and front differential flange. Follow service procedures in section 4A of the Bravada Service Manual.
