Heres the deal, I'm running around town like normal with my newish tires I mounted up last week. coming across a very bumpy intersection with a pothole somewhere in the middle of all the bumps. Right when I ate the pothole going about 35 mph the front left wheel starts wobbling violently shaking the whole truck like it's all over for us. Hit the brakes and slow down to about 15mph and it stops. This is a new one to me. I have not had the oppourtunity to replace balljoints yet but I assume this is a sure sign that it is time to figure it out. I know that spindle nut /washer/ nut combo can't just come loose on me or it would wobble all the time right? There was noticeable up and down play in the knuckle with the wheel off but not side to side like how it acted up. The tires lean way out at top with a full steer and kind point in at the top when sitting straight ahead. Didn't show any of these signs until I mounted up the 15 x 10s... It's had 15 x 8 or smaller most of its life. I still need to drive it out to the shop to fix it.... How dangerously bad could my ball joints be? Could they just let go and fall out? Any tips for first time balljoint replacement? I've got a small torch if it doesn't want to seperate with just the fork n hammer - thats as much as I know.. Thanks folks! - Dave KEEP ON TRUCKIN!
