After hijacking another thread (apologies), thought I'd ask here about a new issue.
I tow a 11k lb toy hauler with a 1200 lb max tongue weight. Pulls OK, and still does. Been driving this '99, L29 K2500, 489/5 spd, since 2014. But recently when no trailer, the rear end feels as if it hangs out to either side for a moment any time steering input is added...such as avoiding water or pothole. Good tires 265/75x 16 on stock wheels. Bushings look OK in both shackles and spring (have new bushings but not yet installed). Tires with 70 to 80lbs. Wheels tight, nothing looks like a problem, but something is. Front end is tight. Cannot see anything amiss. Truck has 160k miles. Never wrecked. Also never drove great, but this swinging ass feel is new. Are the rear spring anti squeaks located correctly? Both sides are the same.
Bought prothane bushings, but sez to remove old bushing sleeves, but the new bushings fit the inside ID of the old sleeves. OEM outside bush 1.68". Prothane OD 1.56". Inside old sleeve, 1.55. '99 year model should be the same as older K2500? It don't seem so. I also have new Moog stock bushings and shackles that are correct. Wanted the poly bushings if I can find them in correct size...or leave the sleeve?
This rear end sway is not apparent when the trailer and trunions are attached. Seems to point to the rear suspension?
Any ideas?
