Going to try to adjust my toe-in DIY. What is the preferred, slightly in, slightly out or completely neutral?

I go for about an 1/8 in toed in

Yeah 16th to an 8th toe in 

I still highly suggest you get it to a shop and aligned properly you'll find out that you might be close but they can get it closer to correct.

If 4wd....the debate of a ZERO toe is ideal. Don Thuren discusses this topic on his tech section in depth to avoid death wobble.

 

I have adjusted mine numerous times to various settings....zero drives the best.

 

I recently had my settings confirmed by a shop, they adjusted a .010 of a degree...just to show a change. Truck drives great and goes straight down the road.

Hmmm. Strange its always the ones with oversized tires and leveling kits that have to manufacture new geometry for the front axle. 

I don't disagree that a alignment shop can get it to spec. Since I have fairly new tires on and the opportunity over the next month to drive in a variety of conditions (empty, towing light, towing heavy, etc) Im experimenting around and I think I'm making progress. On my truck I've determined a 120 degree turn in the adjusting sleeve on the tie rod is around a 1/16th so I've been taking my wrenches with me and tweaking it ever so slightly and I've been happy with the results. I do notice a big difference from empty to towing. It's such a quick simple adjustment I think I'll make a habit to stick slightly more toe-in when towing heavy. I have multiple fishing trips coming up to try this out.

That's why I went to newer T Style vs Y on tierods, it doesn't change your toes setting going over bumps and loaded vs not.

My 1998.5 was number 431 to roll off the St Louis plant at the start of the 24 valve series so it had the T style steering from the beginning. About 10 years ago I was sick and couldn't work on my truck. It needed ball joints and a number of things done so my friend took it to a shop for me to get the work done. The shop screwed up and stuck a Y style pitman arm on it. It steered like dog poo and I noticed this awhile ago. It took me a long time to find the correct arm. Rockauto, eBay and others would always send me the y arm. Finally got the right one.
