I have 250,000 and I want to do a complete steering fluid flush. The fluid has never been completely changed. I have done the turkey vaster method every other oil change but my fluid is still extremely dirty.
Can I run a cleaner through the system? Something like marvel mystery oil or the like? Or should I just drain the fluid to the bucket and keep filling the reservoir until the fluid runs clean?

As always thanks for the input..

 

There is a filter in the reservoir that will dirty new fluid. A new reservoir is needed to avoid contaminating new fluid w/ old.

Also return line must be diverted to catch pan and new fluid added as old runs out. Might require a helper to keep up. It may take a bit of fluid to run clean. I've done this and new fluid did not look pristine, but I only replaced fluid once.

good luck
