4r75e tailshaft bushing help please.
I am currently rebuilding my 75e out of a 04 f150 2wd, I cannot find the correct bushing to replace the one in the tailshaft housing. The part number on the seal is f65p-7052-aa. This seal is listed as an id of 1.598. My local dealer says the bushing is not available but I find that hard to believe. Does anyone know a correct part number for this bushing? Also the part number cast in the housing is RF-f3lp-7a040-aa. I have any info that may be needed to help solve this mystery. Thank you for your help in advance.

Thank you glc. I'm looking for the bushing also. I found one the had an id of 1.606 but not exactly the same as the seal. Would this be correct? I havent put calipers on my driveshaft to measure the exact size but the 8/1000ths kind throws me.

That's the problem I've been running into. The ford dealer doesnt have it listed either. They show it as the complete tailshaft assembly for $200+

How bad is the bushing wear anyway?
I've had seals go bad, but never a rear bushing as they get pretty well lubricated. Not even in my career as a state police officer even with some cars that vibrated at 130 plus have I had a bushing go, but I did once have a U-joint let go and shove the slip yoke into the tail shaft housing and split it. Even then, it being a '78 Plymouth with A727 trans, the dealership mechanic replaced just the tail shaft housing with a used one from an old Chrysler that just did not have the weight bolted on, nor a place to bolt the weight on. Bobby S. (his name) just happened to have a few old transmissions he had "saved" from scrap yards, he did transmission work on the side at home.
