I have replaced a leaking boot over the inner tie rod. don't know how much oil is in there now. How much should i add? Is there a danger if overfilled?

Was the rack covered in oil when you took the old boot off? Remember it uses oil not grease.

When I did mine I assumed there was none left and added the prescribed amount, hasn't leaked any out anywhere. I got an oil gun on Ebay for a couple of bucks, worked fine. When you are finished stand it up in a can or drain it, they will leak if laid down.

After I filled it I turned steering lock to lock about 10 times with wheels in the air to distribute the oil around the rack.

My 02c worth.

Thanks. I could not see inside the rack.

What I did was look at the shiny toothed bit (the rack) as I was replacing the boot, it was dry. Moved the steering so that the shiny bit was exposed.

Was the boot oily or was the oil long gone? My car had been in storage so boot was torn and dry

I've read people use Corn Head Grease.

When I put mine back together after a complete strip down I tried to replace the felt seal where the pinion shaft enters but the new one disintegrated when I tried to reinsert the pinion. I put the old one back in and pumped in the recommended amount of oil. For a few days I was finding drips of oil under the shaft till it found its own level. I figure the felt seal arrangement could never withstand any pressure so must be there to prevent the ingress of dirt. Just to be make it a little more secure I wrapped a few turns of wool around the shaft and forced them into the tube with a piece of thin curved metal. It still won't stop excess oil coming out but should help to keep muck out.
I figure the pumping action of the gaiters will certainly move the oil around but overfilling is never going to be a problem - for very long.
Just my take on the arrangement.

Use what the factory intended to be put in there, Oil, not grease. The new racks are mostly designed for special grease, but the original MG racks are designed for oil. If they leak out the oil, rebuild them. PJ

Some things have changed over the past 65 years. Do you still use straight 30W oil?

Engine - 20/50, - steering rack - 90W, - rear- 90W, - transmission - 90W or modern equivalent multi grades. GL-4 type in transmission. I think I'm correct, that's what I'm running. PJ

I use Valvoline VR-1 in the engine and Red Line 90W in the transmission.

So if you use other then factory fluids in your engine and gearbox why be against a better lubricant in the rack?

If the manual says to give 20 strokes of oil from a hand gun every 3,000 miles they expect it to leak. There is not a huge amount of oil in the rack and might not leak because there is no oil left to leak! The corn Head Type grease will at least leave some lubricant so you don't unknowingly drive it dry.

Some early car owners manuals say if it stops leaking oil or smoking from the exhaust add more oil.

The WSM has been proven wrong before, but saying that, my steering rack does not leak a drop. The bellows on the ends will eventually crack due to poor quality rubber and cause them to leak, but a gentleman from Germany is manufacturing high quality bellows to prevent that. Bottom line, your car use whatever you want, but many have found out that grease in these old type racks is not the route to go. Nothing on these cars are maintenance free.
My rack,

I've taken more than a couple of old racks apart that were pumped with grease. While better than nothing, the grease rarely lubricates the ball ends properly and if used for a long spell usually has wear at the center of the rack and becomes unusable without machining. The corn hole oil might or might not work but I know some 90 wgt gear oil will.

I think you are looking for Declan Burns, he supplies a few hard to get parts. He's a regular here, just use the search bar.
Btw I am quite jealous being at least a year from driving my TF!
