Hawk 289 rear axle and suspension


When I ordered the kit, I also purchased a rear axle from an MGB. It comes complete with many new and refurbished parts. I cleaned it with an orbital sander for the smoother areas and a wire brush in an electric drill for the less accessible parts. I have a copy of the MGA / MBG Owners Workshop Manual (Autobooks 1975). I've copied the pages that cover the rear axle, suspension, brakes and steering. These pages are in transparent wallets that can be wiped clean or replaced. Click to enlarge

The original backing plate for the drum brakes was rusty and muddy. The wheel hubs will not be needed, as the Hawk 289 kit includes new ones.

With the sander, it is possible to bring the axle right back to the bare metal. This is not necessary!

After cleaning, use Hammerite Smooth to paint the axle parts. The wheel hub and the back plate were painted black.

The original wheel mountings proved useful spacers for supporting the leaf springs prior to assembly.

The leaf springs and the (blue) damper arm are now in place, prior to fixing the axle assembly.

That's where the third spring goes - it's for the handbrake cable.

Hubs for wire wheels (of course!) now fitted. Note the serrated nut that fits in the centre. This needs a split pin to stop it rotating and possibly coming off.
