We have gone after "the usual suspects" - wheel balance, inflation pressure and loose scissors. No joy.
I'm now looking at the steering color (P/N 34029), the outer oleo strut assembly (P/N 34080) and the oleo strut steering sleeve (P/N 34057). When I took these apart, I found no grease inside the collar & sleeve. The bare metal on the inside was scored to some degree; we're talking actual scratches here. I put the parts back together with grease, and applied grease through the zerk fittings until it oozed out around the edges. Test taxi showed some remaining shimmy; not as bad as when Opal and I started. When I got the nose back up in the air, I saw where the outer oleo strut assembly would wiggle within the sleeve/collar. I know some movement is needed. How much is acceptable? Would it be worth trying to measure the outside diameter of the outer oleo strut assembly and the inside diameter of the oleo strut steering collar? Would the measure tell anything? Are there wear limits published anywhere (I'll be looking around the pubs I have)? Thanking you in advance for any information. Percy in NM, USA
