LINCOLN-MERCURY 1981-84 LYNX, LN7, TOPAZ Following is a simplified, shorter procedure for replacing pinion seals in these power steering
gears. This new procedure allows servicing of the input shaft seals without removing the gear assembly from the vehicle.
The revised procedure is as follows:
Disassembly
1.
Set steering in straight ahead position and lock steering column.
2.
Raise vehicle on hoist.
3.
Remove bellows clamps and slide below outboard from gear housing. Thoroughly drain and wipe any fluid from boots.
4.
Remove pinion cap. With column locked, remove pinion nut.
5.
Place drain pan on floor below pinion area and lower vehicle.
6.
From inside vehicle, remove column boot from dash panel, and disconnect intermediate shaft from gear (it may be necessary to loosen steering
column to separate intermediate shaft from the steering gear).
7.
Turn gear input shaft to the "on center" position so that D-flat is in the 3 o'clock position and road wheels are straight ahead.

8.
Remove snap ring retaining the shaft seal from the gear housing (Figure 3).
CAUTION: BEFORE PROCEEDING TO STEP 9, PROTECT CARPETING INSIDE CAR FROM OIL SPILLAGE WITH RAGS OR
CARDBOARD FUNNEL. A SMALL AMOUNT OF FLUID MAY COME OUT FROM UNDERNEATH THE INPUT SHAFT SEAL.
