Hey Everyone. Last night I was installing a set of Western Chassis lowering spindles (11312) in m4 84 Buick. I got new bearings ( TMK-SET34 , TMK-SET6 ) , seal ( TMK-8871 ), spindle lock nut and new Powerstop rotors ( PWR-AR-8213XPR ). I had pre So I think I covered everything I would need to get this done properly. When tightening the spindle lock nut I seem to be running out of threads before I can get any, or enough pressure on the the washer (with the key for the slot on the spindle). In fact the key tab in the washer is bottoming out in the slot on the rotor and bending before it gets tight. The nut wont tighten any more and the rotor and bearing assembly still has some play, as in I can slide it in and out by about 3mm-5mm parallel with the spindle shaft. Am I missing extra washers to fill some gap? Did I forget to get something specific parts when using these spindles? Not sure what I have done. Would using washers to fill that gap be a bad idea? I know these parts are sometimes interchangeable with S-10 trucks, do I need something for the truck to make it all work nicely. Let me know what you think. Thanks
