MGB steering rack play

[Buzz]

Any gurus or others familiar with the workings of the MGB rack and pinion? On inspecting my front suspension about a year ago, I found that the rubber boot on the left side (its a right hand drive rack) of the steering rack had torn right at the inner end and was riding back and forth on the tie rod. Since it was near the end I was able to squirt some grease in and reattach it using a couple of tie wraps.

It eventually worked its way off again and now I have some play in the steering. Only with the steering centered, I can turn the steering wheel to the left a good 2.5 inches before the wheels start to move. Turning to the right there is no play at all.

This does not noticeably affect the steering at all when driving except during a transition from turning right to turning left. As the steering wheel crosses center, there is a split second of looseness in feel as it takes up the play.

Standing next to the car with the hood open, I can turn the steering and see that there is no play in the shaft or u-joints, but turning left from dead center, I can see the left tie rod move upwards slightly before it starts moving the wheel. Turning the steering wheel back and forth in the "play zone" makes the left tie rod move up and down about 2 inches in total travel.

Is this likely an adjustment issue, a replaceable worn part or do I need to order a whole new rack?

PS: the tie rod end on that side looks like it needs replacing as well - the rubber is torn. Could that be the culprit?

There is no shimmying or steering vibration at any speed.
