Resistant left hand turns

[00Silverado4x4]

Awhile back I found my truck would from time to time "lock" while trying to turn left, no difference to location, road condition, or temps. Found the pitman and idler arms were badly worn out. I replaced them and all was well again. However lately and now that it's finally hitting colder temps I find that my truck won't turn left easily when first started. I usually turn the wheel over to the right and then it typically will work just fine from there. Sometimes I will have to get rolling before it frees up. It doesn't feel "locked" like it did before but rather highly resistant to turning. So I guess I'll be getting back under the truck again to hopefully find the problem. Again turning right is just fine no matter what the situation, just left, and only when first starting out on cold morinings. I really hope it's not the steering gear going out but I'm not discounting any ideas yet. Any pointers/suggestions before I get started?

 

Thanks ahead of time.

Ive seen a spool valve in a gear box do that too. As stated above your best bet is a professional diagnosis. If nothing else do a good thorough inspection on all front end parts and verify nothing is binding, then head for the dealer.

Perfectly.

 

I was just thinking since I'm about due for my 6k mile tire rotation, brake inspection, I'd go ahead and see what I can see. I figure if there was a specific item that I could possibly take a closer look at while I'm under there. However, I will NOT throw parts at this truck. I haven't got that kind of money. So if I can't find the problem I will absolutely take it somewhere to let the shop figure it out. Just odd how it only happens when cold (relatively) this morning it was almost 60 and it turned just fine...ugh.
