Differential
The differential allows the halfshafts and wheels to rotate at different speeds during cornering.
The differential assembly consists of the following components:
-
Differential case (part of the final drive carrier)
-
Two pinion gears supported by a pinion shaft
-
Two side gears supported by the differential case and halfshafts
When
driving in a straight line, both front wheels rotate at relatively the
same speed. This means both side gears are rotating at the same speed as
well, while both pinion gears revolve (but do not rotate) with the side
gears. During cornering, the wheel on the outside of the turn is forced
to rotate faster than the wheel on the inside of the turn. Since the
side gears must now rotate at different speeds, the pinion gears rotate
on the pinion shaft allowing the drive axles to rotate at different
speeds while still transferring output torque.
Overview
The
diagnostic process for each transmission concern will vary depending on
the symptoms and condition of the vehicle. The diagnostic process
below is an efficient method to collect as much data as possible about
the concern before performing a repair or removing the transmission from
the vehicle for teardown and further inspection...
