IT WAS THE TIRES
oh my god.... TLDR
i got two new (used) tires at the same time as my replacement control arms. when i first got those tires i assumed shitty tire shops balanced them. i recently spray painted my rims and i noticed the old wheel weights were still in the same spot. I came back and asked them to balance the wheels. they visually inspected them, said they were fine, but balanced my old two rear tires for free. whatever, i go ahead and replace my rotors and bearings as they suggested.... got rid of my rotor braking wobble /shrug
a few weeks later to rule out a bad tire, one by one i swapped my tires out for my spare. still wobbling.
a few more weeks later (about the time of this post) i said **** it and paid another shit tireshop to balance those two new (used) tires.... both were unbalanced.... i didnt get a chance to get a good freeway drive without bumper-to-bumper traffic until today and holy baloney, its smooth!
300,000miles: should i try to force some grease into my U joints?
not relevant:
the last month, i had a good moving gig, one day of hell, then dude asked me if i wanna come help unload the truck and he would send me on a freight train home, one more regular work day, and one more super relaxed work day, $1000!
instead i had him send me on freight train up north, fell asleep at the foothills of the cascade mtns and when i woke up my feet were frozen. hang out therefor two weeks, the day i get home, my girl gets paid to drive someone to LA and we hang out in slab city for a week, i get heat exhaustion trying to get a pool pumped out all day in 105+F, and then succumb to covid. my parents say dont come home for the truck (and laundry) until im not sick so thats another week.... so now a month later i drive my truck home and its smoooooooth. man this whole past month, i kept thinking about going for a long highways drive, lmao
something interesting: 2 weeks in my dad reparked my truck and it started just fine. when i came home my battery was at 2volts, headlights were not switch to 'on'.... wtf. i guess im stoked pick-n-pull was out of refurbished batteries cuase walmart replaced mine no questions asked. gonna check my battery voltage around midnight and again at 8am
