To assist in preventing low speed wobbles and to obviate ball end rattles. Experimental Test Report. This joint is identical with that fitted to the spring loaded cross steering tube which has recently completed 10,000 miles in France on 10-C-111. Road Test Report. This promotes slightly more friction in the system which is required to obviate low speed wobbles. It has been run on the road and will have completed some thousands of miles before it actually gets to chassis on test. Weight of Old Part. Weight of New Part. Difference per Car.
