INSTALLATION INSTRUCTIONS

Using your MGB workshop manual as a guide, carry out the following:

REMOVING

1. Jack up vehicle and support with jack stands placed under the rear axle tubing.
2. Remove both road wheels.
3. Disconnect both axle check straps and shock absorber links.
4. Jack up vehicle again, this time support vehicle with jack stands placed forward of the road spring front mount support.
5. Lower rear axle down until road springs are fully relaxed. Keep jack in position. (It may be necessary to remove rear section of the exhaust system to allow L/H road spring full relaxation).
6. Remove "U" bolts, bump stop pedestal, lower shock absorber link plate, "U" bolt guide plates, and spring seating pads. (Recommend working on one side at a time).

REFITTING

1. Coat the nylatron pads with the supplied lubricant. Install onto road spring. (Tap into position if necessary)

2. NOTE: Upper nylatron pad with Delrin "O" ring.

   Lower nylatron pad without Delrin "O" ring.

3. Place 1/2" spacer block on top of upper nylatron pad.

4. NOTE: When installing more than one 1/2" spacer block, simply place black Delrin "O" ring over the 1/2" spacer block center boss, followed by 1/2" spacer block.

5. Install original upper "U" bolt guide plate, followed by "U" bolts with bump stop pedestal.
6. Install original lower "U" bolt guide plate, followed by lower shock absorber link plate.
7. Lubricate and fit "U" bolt 3/8" nyloc nuts. Tighten nuts.

NOTE: Overtightening 3/8" nyloc nuts will only lead to deformation of lower shock absorber link plates.

6. Reverse REMOVING instructions 1 through 5.
