I have greased my slip yoke 4 times using different kinds of grease, but the "slip bump" always comes back. Time to replace. I found one on Ebay, but I am wondering how to identify what I need? Is there a difference or are they all the same regardless of engine or tranny. I have a 2000 F150 with 5.4 automatic. Any ideas what I need to be looking for?
Well, as long as you don't have a 7700 f-150, you have a 4r70w transmission. I will tell you , that replacing th slip yoke does not always fix the problem. I replaced mine and it got a little better but that's it. If that happens, the output shaft for the t-case will need replaced to totally fix it, and who knows how long the fix will last. Try using thread sealer with teflon.
I've greased mine and thought it was the slip yoke, but after hauling a very heavy load I determined that it's the rear leaf springs making noise. Just my $.02
I was pulling a heavy load not too long ago, and when I eased on the gas, something went bang 3 times and then it pulled. Since then the slip-bump has been worse and grease is not helping. Thats when I assumed the slip yoke is bad. So what are the chances that the output shaft in the trans is bad??
