Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Leading evidence: 'Check runout' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'dial gauge set-up' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Check runout' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

1 acknowledgements have no verified action link; they do not establish a repair result.

Outcome without a verified action link

I'm still chasing down a steering vibration, and as far as the hubs go, have replaced both front complete hub carrier assemblies, and this did not cure the problem.

POST 1 / ORIGINAL POSTEROriginal post

Just read something in Excellence when a reader asked if he should upgrade his boxster's brakes to the big red brake system: "...before you perform any work on the brakes, you should measure the concentricity of the hubs as you rotate them. I have seen some that are not round and transfer vibration into the steering system." Hmmm. 1. I am wondering if this is the source of my steering wheel vibration. 2. Any idea how I can measure them to insure they are concentric?

POST 3Original post

i think that advise is total bull****************. you WOULD do it with a dial guage, but i think this is an example of a magazine writer trying to look smarter than he is. it doesn't matter if the hub is out of round, what matters is whether it's out of BALANCE. you won't be able to tell by measuring runout. additionally, even if it WERE a little bit out of balance, its moment of inertia is very small. it's highly unlikely that this is the source of your vibration.

POST 4Original post

I'm still chasing down a steering vibration, and as far as the hubs go, have replaced both front complete hub carrier assemblies, and this did not cure the problem. Prior to this, checked runout on both and it was almost zero. At this point in my case, I've replaced everything up front save for the rack itself, which may wind up being the culprit. I do, however, have to really wonder how even if I did have some slop in the steering rack how that would translate to a speed sensitive vibration. Patrick
