TT Rear axle help
I am very familiar with the regular model T rear axle, but not so much with a worm drive TT rear. Is the design of a TT rear a lot different than a regular car rear other than the worm drive part? I just acquired a TT and plan on doing it up to drive, so should I tear down the rear and rebuild it? It has a Ruckstell. Any help is appreciated. Thanks.

Re: TT Rear axle help
They are completely different. The TT worm drive is very simple and has no adjustments. You just bolt it together. I'm not sure about the TT Ruckstell. That might introduce a higher level of complexity.

The Ruckstell book that can be bought at the dealers covers rebuilding the TT Ruckstell. We make the felt seals that are more correct then the ones in the catalogs. Contact me off line and I will put you in touch with Tom who makes them.
I know the voices aren't real but damn they have some good ideas!

Re: TT Rear axle help
I HIGHLY suggest tearing into it. I just tore mine apart and found every single one of the differential carrier bolts spinning. Luckily they had cotter pins preventing the nuts from completely backing off. I found one differential bearing almost falling apart, one trashed Hyatt bearing and some bad seals. It’s going to take a little more time and money than I had first anticipated but it’ll be 100% rebuilt and it gave me a reason to install a new to me set of 5:1 high speed gears.

Here’s a link to one of my very sloppy bearings.

Re: TT Rear axle help
Welcome to the TT club
Search the forum here and the previous one too for TT topics, there is a wealth of info and advice. (for example: viewtopic.php?f=2&t=13093)
Yes, you would be wise to pull down the axle and inspect it at the least. There will be worn parts, but at the minimum, a good clean out of sludge is important.
Two suggestions: buy the MTFA Ruckstell book (latest copy is best) and secondly - beware it is HEAVY, so you will need help and a strong work bench.
And a third bit of advice - don't worry too much, it isn't all that hard to do (especially with the book as a guide and asking here for anything you are not sure of).
All the best
