Lada reinforced idle steering arm with tapered bearing 

The original idle steering arm has plastic bushings for bearings. They create to much friction and go bad rather quickly. I think you can by a better one with some roller bearings inside , which will be an improvement, but if you want something that will last, you need the thing below. It is simple to fabricate and uses tapered bearings, that can withstand a lot of load. The preload on the bearings is adjusted using stock front hub nut.
