So I have been trying to narrow down a shudder I get whenever I hit large and small holes, go over bumps at speed etc etc. I started with replacing all my shox bushes (front and back) -no change.
I then checked one side of the cars rack ends and t-rods -they needed replacing so did that -still the shudder continued. I was then convinced that I needed to replace my steering rack bushes -so I did the easy one first -the large grommet ... no change.
Convinced it was the remaining 2 bushes, I took the plunge this past weekend.
Since removing the steering rack has been covered in other forums I shall not cover it here -only to add that to remove it easily (for HD-FTE engines) I removed the rack ends and the hose connected to the radiator -and it came of very easily!
Anyway, prior to removing the steering rack, you must obviously disconnect the intermediate shaft ...
when I grabbed it, I decided to wiggle it back and forth... -I got plenty of play and it seemed to make a knocking sound. So I asked my
to grab it and give it a good shake as I held onto the steering ... indeed, it appeared that the knock could be felt all the way to the steering.
So, I then suspected the grommet was bad -basically this part ...
so I proceeded to disconnect the intermediate shaft. once removed, I took it to my mech for a thorough inspection and he told me that it was good as new. He informed me that I would have to inspect the main shaft -this meant removing the entire steering column.
So I went back home and pondered on my next steps ..... and read up on this View attachment steeringassembly.pdf
