I love my '01 standard cab, 1500 4wd with 182K on the 4.8 and have kept her in great shape and do all the scheduled maintenance. I do run MTs on her and have a 2" lift/leveling kit on her, but everything else is stock. Sure I have a few beefs like the brake lines that don't hold up to a week or two of beach salt a year and I had to replace them though I had quite the fun doing so. Anyway, my question is in regards to the front end and suspension and what I should do to keep her running well, safe and for a long time to come. I noticed a few months ago that every other lug on the front tires is wearing in a high/low pattern on the outside edges which typically denotes the truck being out of alignment or having incorrect toe-in. I have had these checked by two different shops with no issues found (I hate that this is something I cannot do myself). Anyway, I have noticed the ride getting a bit sloppy in the steering and control arena when I come over a hard-ish bump like a highway bridge expansion joint that isn't the smoothest at high speed; a bit unnerving I'll be honest. Everything looks tight and secure under her, but I'm no expert. As far as the front end, I have replaced the shocks in the past and once the tie rod ends as the joints wore out.

Any ideas on what needs to be replaced up front or checked? Thanks in advance guys!!!!
