There are two separate fixes, one works for sure, the other is a maybe
First, the maybe fix. Ford no longer stocks the parts -- however, the Ranger is actually made by Mazda and, according to their parts store here, they have the parts for special order (driver seat about $40, passenger seat about $38). I didn't go for it because the drawing doesn't look like the same part, although it is in the same place, etc...
Now for the one I know will work. Total cost under $10 and I'm about to save you a ton of experimentation -- I tried eight different methods and only one works (pictures of all available, if you are interested). I'm talking about the passenger seat. I have yet to fix the driver's side, but will do that and, if I find anything difficult, I'll post the differences.
I assume you have removed the seat. To totally access the area, you must release the level held by a torque head bolt, remove the four bolts (10 mm) holding the seat to the rail mechanism (careful about the forward adjust lever, the damn thing releases fast and can give you a whack). Then, with access to the nut (also 10mm) that holds the reclining mechanism on the seat track removed, pull the apparatus far enough down to remove all the shaft and any broken parts. (you will have to open the two ears holding the action wire in place eventually, might as well do it now). My part was broken in two places. The shaft was separated between the outer pivot point and the remainder of the shaft. Further, the part (lever) that actually hooks into the release wire was separated from the remainder of the shaft. After trying a bunch of different fixes -- all failed. I decided to put a steel pin in the broken shaft and create a metal fitting that went over the outer shaft and was pinned to the lever to bond it with the outer shaft. This would have worked, except there is torque from the cable that twisted the part enough to allow the pins to let go. Back to the drawing board. (see pics 361-363, below)
I changed out the pins for small bolts and the metal plate for a half-inch fender washer with appropriate holes drilled to match the lever arm bolts plus one from the lower flange on the shaft to bond the washer to the shaft itself. (picks 364 - 368). This worked once and then the shaft separated at the original break point, backing off on the steel pin I had placed there. So, one more operation -- I drilled a hole completely through the shaft endwise and installed a three-inch, number six machine bolt and nut (the nut has to go on the outside). Caution, the bolt heads in all cases go on the inside of the fitting. There is plenty of room on the outside to work.
With the half-inch washer as the base and bolts holding everything together, nothing bends and the repaired fitting works fine. You will have to spread the ears and release the cable anchor to put it all together, resetting the anchor after everything is in place. So, for the price of four machine bolts and some minor drilling, it is stronger than the original and you are good to go.
For some reason I can't attach the photos. If you will E-mail me direct (
rjonesassn@aol.com) I'll send you the file with the pictures.
Addition: I fixed the driver's seat today. Simple break of the shaft, all else was OK. Removal is like above. Drilled the same hole through the shaft endwise, installed the 3 inch machine bolt and nut, tightened it down and re-installed everything. Fix cmopleted.
Good luck!
