1955-57 RACK & PINION STEERING THIRD U-JOINT SHAFT SUPPORT UPDATE

1955-57 RACK PINION STEERING THIRD U-JOINT SHAFT SUPPORT UPDATE In the February 2007 Classic Chevy magazine we introduced a support bracket and U-Joint to be added to the shaft that connects the steering column to a rack and unit. This bracket bolts to the inside of the rack and crossmember and supports the steering shaft so a third U joint may be added to clear some types of headers. The measurement of the frames on the Tri-Five cars varies slightly where the rack and crossmember bolts on. This changes the angle slightly on the third U-Joint bracket the shaft from aligning with the lower U-joint on the rack itself The updated PIN 57-175693-1 now includes six washers allowing the bracket to be shimmed so the steering shaft will align Parts List 57-175693-1 955-57 Rack Pinion Steering Shaft Support Bracket U-Joint Kit Tools Needed: 916" Wrench916" Socket Ratchet Time Frame 3 Hours Image 1: The CCI rack and kit uses a bolt-in one tubular crossmember to hold the rack and in On the drivers side, the crossmember bolts to the frame using the holes in the frame where the steering box bolted on. On the side, the crossmember bolts to the frame using the holes in the frame where the idler arm bolted. Image 2: Chevrolet was not too concerned about the measurement between the frame rails where the steering box and idler arm bolted on. You can measure ten different frames and get ten different measurements. In addition, one and two-piece frames have different widths in many areas. Since the frame measurements can vary up to 34", the rack crossmember is designed to work with any frame. The mounting ears on each end of the crossmember are leaned inward slightly and into when bolted to the frame. Image 3: The new third U-joint support bracket bolts to the two forward bolts on the driver's side and supports the steering shaft. Image 4: With the shaft installed in the column coupler and the new U-joint bracket, it must line up with the lower U-joint or the s haft will be in a bind. Image 5a, 5b: Use the six fender-type flat washers to shim the bracket into The washers can be between the bracket and crossmember to align the shaft with the lower U-joint. Experiment with different combinations of washers under one bolt or the other or both until you are happy with the alignment. data-pb-style"636B5E094A31F"justify-content: ; ; ; border- : 1px; : 0px 0px 10px; : 10px; data-pb-style"636B5E094A32A" border- : 1px; : 0px; : 0px;
