41–01 Driveline Inspecting and
Lubricating
Inspecting
Before lubricating the driveline U-joints and slip-
joints, make the following checks:
1.
Check that the yoke-strap capscrews are tight-
ened as follows: See
, Ref. 4.
•
Spicer SPL90 and 1610: 50 to 60 lbf·ft (68
to 81 N·m)
•
Spicer 1710 and 1760: 125 to 135 lbf·ft
(170 to 183 N·m)
CAUTION
Do not overtighten the yoke-strap capscrews, due
to the extreme load occurring at high-speed rota-
tion. A loose or broken capscrew at any point in
the driveline weakens the driveline connection,
which could eventually result in serious vehicle
damage.
