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.

The arms are cheap and can be changed quite simply.
Leading evidence: 'Replace quite simply' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace quite simply' (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.
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.

Hi,
there seems to be a lot of issues with the front tuning fork arm / control arm link / thrust arm or whatever you want to call it.
Would just replce the bushings work?

instead of the arm:

Reason would be to replace with a high quality bushing, actuall arm is probably gine.
The original bushing is actually a spherical bearing that moves freely and does not put torque on the arm in any position. Replacing this with rubber or poly will affect the torque on the arm as it articulates which can't be a good thing. Quite honestly these are not that hard to replace and the original arms (or aftermarket replacements Meyle, Delphi, etc) are not that expensive.
that is a good point, I will either get a a stockish arm or an aftermarket.

about twice the price of the Mahle.
2nd. Putting an elastomer bushing in this place changes the effective spring rate of the car, and puts different loads on things than the original spherical bearing. Not necessarily right or wrong, but not something to do without considering all the pros and cons first. The arms are cheap and can be changed quite simply. You'll need an alignment afterwards though, since a minor change in length of this arm significantly affects the toe setting.
