On my short arm kit my lower arms are moving at the mounts. The joints are not broken but the bolts actually move inside the mounting holes, is it suppose to be like that or should i just swap over to a radius arm style.

 

How you torqued them down? If the bolt is moving it may not be tight enough, or your bushings my be warn out

 

bushings arent worn i checked but it maybe possible the bolts may be worn and are just backing off i am going to go and get new bolts and nuts tomorrow and cover them in some thread lock and see what that does but has any had the bolts holes warp into a oval shape allowing the bolts to move.

 

is this at the axle mounts or the frame mounts?

 

there is movement at both the frame and axle

 

you could weld on a large washer on the frame end, but the axle end is a little more difficult.
you can replace the axle mount with a stronger heavy duty one available from most off road supply shops.

 

i know rustys had axle mounts just had no idea how to go about the frame mounts i will give that a shot tomorrow
