Lock washers would be acceptable, if you thought it might come loose.I usually add them just in case.
thx 68amxgopac! we'll do that.
we just solved the steering problem last night ... well actually this morning at about 2am after spending a couple of hours figuring out how to get the pitman arm off and then several more putting the new one on.
it was actually lucky that kyron figured out from the motion of the pitman arm that it would likely be the source of the problem because the tsm is a bit vague (for newbies anyway) about this. point #3 in their diagnosis has a sentence about checking the steering linkage which could involve a lot of components, but he noticed a horizontal slide in the pitman arm.
most of our woes, advice received and solutions are described here:
http://forums.amceaglenest.com/index.php?topic=24041.0the experience was a multi-instructive one (eg we learned how to load and use a grease gun) because the difficulty putting the arm on was due to the very low tolerances involved in the fit. we were able to use a bit of brute force to get the old one out, but that was because it was slightly worn. it would not have been wise to force the new one in because we'd have likely damaged something. neither the tsm nor anything on the web mentioned the idea of going after the tie-rod on the drivers side though this was really the most logical avenue of dealing with the situation - i think we were reluctant to doing so because
a) it wasn't in the tsm
b) it wasn't on the web anywhere
c) mostly because we were frightened by the prospect of tackling yet another rusty nut, bolt and formidable cotter pin (in fact, as i pulled on the cotter pin i managed to cause the wheels to come towards me
)
the way we got the pin out was to use an awl through the loop end (since pliers just couldn't hold on) and making enough room to get a small punch in to work it some more. then eventually we got a larger punch in there since the thinner one was bending.
the other problem we encountered had been with getting the old pitman arm out - the pitman puller worked fine at the steering box end, but the other end is cone-shaped too so it sticks in pretty strongly. apparently there is a tool that looks like a two-pronged fork with both tines shaped like wedges which you can hammer in, but we didn't have one, so we stuck in 2 chisels and hammered alternately on them.
we took kiyreagle out this afternoon and the steering is excellent and very responsive! the wheel is a bit off-center, but that should likely be a simple fix possibly related to the tie-rods adjustment which would likely align the steering system more optimally.
