Steering-Rack Boot Replacement

The O/S steering-rack gaiter, which is a rubber boot that holds grease around the rack, was leaking and this was an MOT failure so before turning to any Subaru garages I shopped around online and got a pair of the boots for £12 from PartsFromJapan.co.uk, who have an amazing selection of the smaller, rarer parts and, with a little help, managed to get the O/S one on in under an hour.

PROCEDURE:

1. Jack the car and get the front wheel off, on the side you're doing the boot on obviously.

2. Take off the front under-tray by removing the two 12mm bolts on the centre cross-member, two 12mm bolts beneath the front lip and the two 10mm screws at the sides.

3. Linked to the hub, just behind the front-edge of the brake-disc is the track-rod end, which runs up into the steering-rack. You can see the rubber-boot over the far end of the track-rod, covering its join to the rack-body. [Mine was split totally in half as you can see below and had seeped grease everywhere.]

4. Using a 17mm open-ended spanner undo the locking-nut holding the track-rod to the hinged mount on the hub. The nut is facing the hub not the rack so if you're facing the brake disc it un-tightens clockwise. The track-rod will likely rotate and move up and down on its bushes so hold further down the rod with strong-grips [or a funny sized spanner if you have one, we got one to fit but its not metric and doesn't have a size printed. I also ended up bracing this against the thick hub-frame to get enough turn on the big spanner to crack the nut.]

Once the locking-nut is turned only slightly, it should allow the track-rod itself to turn freely, anti-clockwise, out of the hub-mount.

5. Open the finger-clip holding the near end of the rubber-boot and slide it off the rod. Undo and dispose of the clip or tie holding the large end of the rubber-boot on to the rack body. Cut open the rubber-boot and slide it down off the track-rod. [Mine had been split, and the rack exposed, for quite some time so I cleaned off all the dirt and grease I could with a rag - thankfully no gravel has got into the steering!]

6. Re-grease the rack and smear a few blobs of grease around the inside of the new rubber-boot. [We used Castrol LM Grease we had lying around. I'm not sure what Subaru suggest, but any thick engine grease will do.]

7. Slide the new boot over the track-rod end, working the narrow part over the locking-nut, and up into position. Replace the clip/tie from the large boot end with a cable-tie, then slide the finger-clip back down the rod and re-fasten it. Screw the track-rod back into its mount and tighten the locking-nut hard anti-clockwise. Replace the wheel and front under-tray.

This is a relatively simple job, done in an hour with just a few spanners and would no doubt cost plenty at a garage, let alone one of the 'Subaru' ones!
