Disc to Hub bolts & nuts orientation

[andrewk]

Hi,

I’ve seen pictures of two different ways the bolts and nuts attach the disc to the hub, most commonly with the nuts facing the front (picture 1).

However originally on my car and other pictures of unrestored cars I’ve seen, the bolts go through the disc and the nuts secure from the inside (picture 2).

The manual says “bolts fit from outside to in - knock on wheels”.

Therefore is the correct way to secure the discs as in picture 1?

Sorry if this a naive question and any clarification is appreciated.

Many thanks,
Andrew

Photos show my three E-types, 2-3.8's and 1 4.2, (all series 1) had the nuts on the outside, nearer the wheel.

I'm not asserting that was correct, just how they were, and how I replaced them when changing out discs.

All the photos I could find online during an admittedly short search showed the nuts to the outside, as your first photo.

Perhaps the specified orientation changed somewhere during the production run?

Dear Steve & Steve,

Thank you both for your input.

I can't find anything in the Service Manual for cars with wire wheels.

Interestingly, I found two separate listings on Ebay for hubs & disc with the bolts going through the discs.

Assuming your cars have non vented discs, it does make me wonder if the orientation of the nuts & bolts was changed by the factory on S3 cars because they are vented?

I'm hoping others can chime in on the topic, even if its to confirm that it really doesn't matter which side the nuts and bolts go?

Many thanks,

Hi Andrew...for cars with steel wheels the bolts came through the discs from the rear....with wire wheels is threre a possible contact with the wheel if bolts come from rear....Steve..PS iv posted this on JL as it got me interested https://forums.jag-lovers.com/t/s3-fron ... lts/472250
