rerend wiggle

This is my problem i'm having when driving on the interstate or city driving i can feel a wiggle in the rearend and when i go to stop after awhile the rear breaks feel like they are worped but the peddle doesn't move i have drum breaks in the back this has been going on for about 2 months i just got my brand new leaf spring from the recall put in last week and that did'nt help i need some help it's driving me nuts i dont know if it's the wheels or the tires i realy hate to bring it to toyota it will cost me a fortune.

 

You're saying this was an issue before the leaf spring replacement and is still there? It sounds more like a steering or alignment issue, if so. Is the truck lifted? Have you had it since new? What other work has been done to it before this problem started?

 

Double check your u bolt torque, try 85 ft lbs on the 4 nuts under each spring pack.
