Gojira94 Posted December 31, 2022 Share Posted December 31, 2022 87 MJ Base, originally 2WD 2.5l 4-speed, no tilt, with power steering. 1987 Parts manuals show same 2 shaft options 52001947, w/out power steering; 52001948 w/power steering for a 4.0 5-speed, so power steering seems to be the differentiator between the 2. The 1947 and 1948 are 570mm. Upper steering shaft for non-tilt columns shows 83502100 for any/ all 1987 applications, power steering or no. At least for 1987. 1986 goes down a deep rabbit hole of shaft combos. I received a new Crown 4713943 intermediate steering shaft today. This part cross-references with OE part (don’t know- at first thought 52001947). The flat spots on the double-D end and splined end are (almost) perfectly 90* offset from each other. The old one has them maybe 80-82* offset. Uh-oh. The flat index spot on the steering box input shaft is at 12:00, Pittman arm is perfectly straight, wheels are straight, steering wheel is straight but I don't recall if the splined steering wheel end is indexed on the upper steering shaft. Steering wheel, upper shaft and lower shaft all agree and mate to the steering box with what's there now. However, any or all of these 3 may have come from almost any other MJ/ XJ from 86-94. The column housing even may have come from something else. I suppose I may have a set of some 1986 parts (2 different parts 570mm bolt hole center to center, 580mm bolt hole center to center, each, for w/ PS and w/o PS, for a total of FOUR lower shaft options for '86). The 83502100 upper shaft matches the 570mm lower shaft, 82600223 upper fitting the 580mm lower. Crown makes a reproduction of the 83502100 upper shaft, with the same part number, and specs it for use with the 570mm lower shaft. They do NOT make the 83500223. 1986 no tilt/ floor shift option combos: Shaft, Steering Column Upper (Item 16 in 1986 catalog) 83500223 SHAFT, Steering Column Upper With a Lower Shaft Length of 580mm (Item 24) 83502100 SHAFT, Steering Column Upper With a Lower Shaft Length of 570mm (Item 24) Shaft, Steering Column Lower (Item 24 in 1986 catalog) 52001044 SHAFT, Steering Column Lower 580mm Between Centerline of Mounting Holes (With Power Steering) 52001045 SHAFT, Steering Column Lower 580mm Between Centerline of Mounting Holes (Without Power Steering) 52001947 SHAFT, Steering Column Lower 570mm Between Centerline of Mounting Holes (Without Power Steering) 52001948 SHAFT, Steering Column Lower 570mm Between Centerline of Mounting Holes (With Power Steering) I'm going to go do a side by side comparison and see what I can figure out...
