Section 4
Assembly and Installation
23
Assemble Differential Case
WARNING
To prevent serious eye injury, always wear safe
eye protection when you perform vehicle
maintenance or service.
1. Apply specified lubricant on all parts of differential
case assembly before installation.
CAUTION
Never attempt to press a cold ring gear on the
flanged half of the differential case. A cold ring
gear will damage the case because of the tight fit.
The tight fit can cause misalignment or excessive
runout and will make final backlash and teeth
contact adjustments very difficult.
WARNING
Wear safe clothing and gloves to protect yourself
from serious personal injury when you touch the
hot ring gear.
2. Expand ring gear bore by heating ring gear in tank
of water heated 160°F to 180°F (71°C to 82°C) for
10 to 15 minutes. DO NOT USE AN OPEN
FLAME SUCH AS A TORCH FOR THIS
PROCEDURE.
3. Install ring gear on case half or in the integral
differential case.
WARNING
To avoid serious personal injury be careful when
using Loctite or Three Bond adhesive during
assembly and installation procedures. Follow the
manufacturer’s instructions for safe use to
prevent irritation to eyes and skin. Wash after
skin contact. If the Loctite or Three Bond
adhesive gets in the eyes, flush the eyes with
water for 15 minutes. Have eyes checked
by doctor.

4. Apply Loctite 271 or Three Bond 1305 adhesive
to ring gear fasteners. See Section 3, “Liquid
Adhesive.” Install ring gear fasteners and fasten
with the specified torque, 66-75 lb-ft
(90-100 N•m). Figure 4.1.
5. Assemble new cone bearings in both halves of
differential case or in both sides if it is an integral
differential case. Figure 4.2.
