well i know its been discussed before but when i come to a stop waiting at a light and then take off again feels like something slips then i get a bump in the drive train.

Only thing I'm wondering is if it is a trans problem or the slip yoke on the drive shaft.
wouldnt surprise me one bit if it is the trans but since this new drive shaft that is when i have noticed all the issues.
Any input? Does it all the time, unless i accelerate at an extremely slow rate.

 

It's usually the slip yoke splines.

 

Did i read that you greased yours before bob?

 

ahhh, the call of the slip yoke

 

I did regrease the slip yoke on my Trailhead (2WD) but it only helped for about 2 months. Ford sells a special PTFE grease for the slip yoke and that's what I used ($25/can!). When my LII started doing it, I slapped on a set of JD's and it has never done it since.

2WD is easy because the slip yoke just slides out of the trans tailhousing. The 4x4 yoke is more of a hassle. It's in the main driveshaft and you need to pull the accordion boot to grease it. From the factory, the boot is held on by special crimped clamps that take a special tool to set them.

 

I think my first attempt will be to complain to the company that made my driveshaft...

Maybe they could put some type of grease fitting in it.

I guess that is where i will start, was just worried that it could be tranny.

Thanks!

 

my mustang does that when I'm at the track.

 

my truck does that every now and again........i think it is my tranny starting on its last leg...

 

My truck does that EXACT same thing Zach. It is rediculous and I have been chasing it for years.

The only time I have ever gotten it to go away was when I greased the slip yolk and changed u-joints... so I guess that is what it is.. though I also suspect the trans could be the problem too..

Just felt like adding to the topic... not that it helps.. lol..

 

i can tell we are all hoping its not the trans. lol

 

Just pray it's not the trans

 

ITS NOT THE TRANS lol, grease the slip yoke man and check your Ujoints for binding

 

mine did this for a while, especially when it was cold, my tranny fluid was low and would contract in the cold..after the tranny fluid was topped off i started getting a really bad squeek or screech..ended up having to replace my torque converter.

 

Just turn up the radio and it will all be good.

 

haha hey im just taking the lazy route right now, see what input everyone has
