I love the idea, but sadly it's a no-go for JODB.

No, I like to keep the immobiliser.

Having a young child (now 14 months), has meant that my priorities have massively changed, as I'm sure many can relate to.

That said, I've managed to find some time to book a track day at Anglesey on 30th October.

I've also ordered, received and installed a Horse Clock, which is a genuinely fantastic piece of kit. I'm really very, very impressed with it. It works perfectly with the Celica 190ECU and my 2ZZ engine, despite not being designed for it.

Will post a full review in a separate thread, but it's highly recommended.

Brilliant, thank you.

I've ordered a seal puller to make it easier too.

As Carolyn said - have done it this way a few times.
It's ideally a 2 person job, never attempted to do it on my own.
Be careful when putting the shaft back in - that's when the seal can get damaged (don't ask how I know).
In general, these seals are quite fragile and I was getting a new one every time the shaft was out.
Cost of seal vs. the hassle to go and re-doing the whole process and you'll have to get a new seal anyway.
Do it once and right.

Quote from: Nomad on October  3, 2026, 00:20Two months later I finally got around to check the level of transmission oil and refill if necessary.

By closer look it turned out the root cause of the leak wasn't the drain plug but the seal which sits inside the gearbox. The flange on the CV axle was crashed I assume by a ply bar when the previous owner tried to remove the axle to replace the boot (I've seen a receipt for that). And the damaged edge has cut into the seal.

Question, to replace the seal I need to pull the axle out. Do I need to remove all 3 arms attached to the wheel hub and the strut. Or is there an easier way?

Remove the bolt connecting the arm that goes from the chassis to the hub.  Remove the bolts at the bottom of the strut that attach it to the hub. The assembly will swing away far enough to get the axle  out of the gearbox.  I think it helps to detach the caliper from the hub too.

And cheap as car parts go.

Well done for getting to the bottom of it.  That's a lesson for all of us!
