Drive shaft rumble

This happens when driving around 30-40 kph and foot off the throttle. Going down a gentle incline and foot off throttle at low speeds also does it. It sounds like the drive universal joints are a bit...

The ring gap will seldom change down the bore. The ring wears and opens up the gap. If there is wear in the bore, you will feel a lip just above where the ring stops at the top. No step, bore ok.

Sorry you are correct, from the web Example: 4" (bore) x .0035 = .0 14 minimum gap. I work in mm so I didn't click that .014 was wrong figure.

I agree, if any flowing occurred, tires would not last 50000 km or more than a few months.

I should have included the article, but it is anecdotal. Has the rubber "flowed" into this new shape ? Has it been bent past its yield point ? What has actually physically happened to the rubber. Can...

Things change shape when you exceed the stress point of no return. Standing for months does not make the rubber bend past its point of no return. So if you say it developed a flat spot, what has...

I went from 16 to 18 on a 1998 986. Main reason was the over read by nearly 10% on the speedo.

Went up to the next size tire and now only 2-3 % out. Any bigger and it scraped the inside of the...
