Default Slippage and leak issue!!

I've only had this for 2 days, here are my issues:

When I come to a hard stop it feels like the tranny or something is catchin up, and same when I go from a start there is a small slip. Is this a tranny, u-joint or possible rear end issue? Regular shifts while driving are smooth as butter, and tranny goes into, park, reverse etc with no problems.

Now I noticed a leak coming from the driver side rear tire/axle area, its gear lube for sure.

Are these 2 issues related or 2 seperate problems?

Truck is a 2000, 3.0 V6, auto, 102k miles, 4wd.

i think your truck has a vss (vhicle speed sensor) at the top of the differential. it is not on the drivers side though it is right above the ujoint. these are a common problem but they usually don't leak. they can mess with your shifting and the speedometer can get screwy there is a wire going to it. if it is that it is an easy $20 fix. i don't know much about the differential someone else will probably chime in ..... if your u joints go they usually make a clunk when you put ti in gear, however on there own they would not casue an oil leak

A buddy said it is probably some sort of seal. I'll have to see how much of a pain in the ass that is to change...

ill look into the shifting problems from that speed sensor, it would be nice if thats the issue

x2 or rear wheel cylinder.


The other issue you're having: description given is hard to really 'visualize' or 'feel' to me. Sorry. Will say though, if an abs speed sensor is malfunctioning, the ABS will do it's shaky pedal crap more often and under normal brakeing OR won't do it at all under hard braking when it should engage.

I'm gonna pull the wheel off today after I do an oil change to gert a better idea where its coming from.


As far as a better description of the slippage I'll try again:

If I come to a sudden or faster than normal stop, it feels like something has to catch up with the truck, I dont know what is trying to catch up though, it feels like somthing slips back into where it should be, like first gear or there is slack somewhere. After being stopped, under any condition, something slips before power hits the wheels.

I do notice a small pulsation on the brake pedal. I cant really see how ABS would effect power transfer to the wheels, but I've never owned a truck either.

Thanks for all the help so far

afew thoughts. gear oil suggests differential leak. weird brake action can be caused by the abs/vss on the differential. if you have a leaking wheel cylinder that is a separate issue from the gear oil leak. get under there and take a look. the abs/vss in the differential feeds the pcm info so when it is not working it feeds the wrong speed info to the pcm and then the pcm sends the wrong info to the tranny and it does not know what gear it should be in ......I think these abs/vss in the differential where only 1998-2000 but they are a common problem. check your speedo and see if it works properly. any clicking sounds from the dash when you apply the brake? those are abs/vss symptoms ...remeber to post what happens

its definitely just gear lube, no brake fluid...my buddy is gonna come down later and help with getting the drum brakes off, Im used to only ever having disc brakes so drums are a new thing to me...I think I'm gonna replace the VSS anyway, its cheap. I did notice once or twice that the speedo didnt move as smooth as it should, kinda jumped almost... After we get this stuff pulled apart I'll be posting.

Also is this safe to drive on? Obviously i know i probably shouldnt, but I do have a job to get to. Its only 7 miles one way.

If you have ramps back the truck up on the it makes changing the vss you need a 10mm socket to remove the one bolt then the thingd pops off. Make sure you clean off the area that it sits on it has to sit snooth on the differential it is safe to drive as long as there is gear oil in the diff. You can pull the plug on the diffyou should feel oil if you stick your finger in it keep us posted

Thr vss is on 10mm bolt pop the vss of clean area install back up on car ramps if u have them. Safe to drive just make sure u have gear oil in th diff. You have to pull the axle to change the seal

I replaced the VSS and nothin really changed except the speedo is perfectly moving now. I still have that hard engagement when I come to a fast stop or whenever I go from a stop then forward there is that slip.


I checked my diff and the fluid was fine, it didnt seem hardly low at all to me. I added a little to comp for what came out. My buddy and I are taking a look at it this weekend. I bought the rear seal just in case.


Back to the slippage. While I was under the truck, I could turn the driveshaft by hand a little both ways, is that normal when its in park? It didnt seem like any of the u-joints where going bad on it. Of course thats hard to tell when the whole shaft moves.

well at least you have one issue taken care of. the vss ties into the abs and the pcm so that needed to be replaced. I dont know much about the tranny or the differential but on my truck that driveshaft moves back and forth a little also.
