The steering box on my Fairway (and most probably yours!) has always leaked slowly. It’s usually after a drive when the fluid is warm and results in much embarrasment when you reverse out of somebody’s driveway and leave them a small puddle of Dexron oil.

However after a long run the other day, I parked up in my garage and found a larger than normal puddle of fluid underneath the box the following day. In fact, the leak was so substantial that the power steering no longer worked. I could see the leak was coming down from just above the output shaft, most likely from a bad seal inside the steering box.

I’ve purchased a seal kit for the steering box, however it looks like a fairly tricky job to tackle. The steering box needs to be removed, which I imagine is going to prove challenging with seized nuts and separating the ball joints from the track rods is always a faff. The replacement of the seals needs to be done carefully as there are a fair few parts which need to be dismantled in the box and reassambled in the correct order!

With that in mind, I have tried using some Wynn’s Stop Leak; though I fear the leak is too much for this to have any effect. Because it’s the middle of summer, I wanted to try this approach first, before taking the taxi off the road for however long it takes to replace all the seals.

Please let me know if you have any experience with these leaky boxes and if you’ve replaced the seals on yours, I would love to hear from you!

Update 27.07.22 The Wynn’s Stop Leak didn’t work – I have replaced the seals on the output shaft of the steering box and the leak has stopped. The old seal had perished and was letting fluid out. I have written up the entire process here.
