I find this makes a big difference because it lets grease get down into the kingpin and for kingpins you should use a graphite base grease because it will coat the bushing.

Arvin meritor wants king pins greased with the vehicle weight on the wheels. This forces the grease to flow through the thrust bearing instead of purging out around the bearing, which is what happens when the front-end is jacked up (weight off the wheels).

Keep in mind - the grease goes through the bushing before the thrust bearing.

You should use a NLGI #2 EP grease... IMO.

Could be worn tie-rod ends or pitman arm. Any good mechanic can find the problem easily.

dawn If you mean by "loose" steering the truck tends to wander all over the road and follow the pavement seams, try raising your steer tire pressure. I normally run 110-115 cold in my steers, and seems to help a lot.

Even though I have one, I don't think having a Frieghtliner has much to do with it....JMHO!
