Hi I am in the process of building the non-suspension chassis. I thought it prudent to test 'modules' as completed. Found a snag with the rear most steered axle (if my oreintation is correct). The tiebar for the steering snags on the drive gear in the differential, not the differential but the gear (20 tooth?) that drives the differential. Had some problems with the tie bar snagging on the structure which prevented the steering from working. solved that one, Now if the drive to the differential is engaged and steering takes places loud clinking can be heard as the tie bar fouls the differential drive gear. Has anyone met this problem, if so did they find a solution? Hoping someone can help, thank you reading this post. Solved it.
