68 third member leak
« on: February 06, 2025, 09:19:20 AM »
I replaced the pinion seal on a 68 third member and the seal is not leaking but is leaking around the pinion yoke nut. I have replaced pinion seals before and not had this issue. Do I need to add thread seal to stop this leak.

It is recommended that a new pinion nut be used that has sealant on the threads (typically red in color).
1968 CJ - Owner and paint original. Dec 67 build in Dearborn. One of 50 135 Cobra Jets. Ford engineering used it for 8 mos. to resolve problems in the 50 early car build. Ford by-passed the normal sign off to get cars to the Winternationals drag race.

 Ok, Thanks I will try that. Strange that I have not had this happen before.
