Axles shooting grease upon stumble....Confused

2001... 3.8 97,000 miles non supercharged

I have posted a few times, about my car stumbling at around 12 mph and then again at 18 mph..when i get to 18 mph and immediately release the gas pedal the engine or trans will stumble hard. Only when the car has warmed up.

I decided to jack the car up and get the front wheels off the ground to check voltage and to visually see this happen in action.... when it gets to 18 mph it will stumble and shoot axle grease near the radiator bottle simultaneously..the driver side also but a small amount. I noticed it was some grease already Underwood, so this has probably been occurring , just when the wheels were off the ground no pressure on them, it allowed the grease to shoot out freely.

Now if it was the axles that were bad it would happen all the time I'm guessing..so Its the trans or some sensor making the trans shift erratically. Is shooting grease out normal when having the tires off the ground.

I changed fluid and filter a few weeks ago and it didn't change the condition.

My question is , is their a way to re grease the axles ( have them service) because they both lost some grease. What should I do now. their are no codes I guess a trans shop will be my next stop.

So its slinging CV grease from the boot, or is it trans fluid? As far as regreasing the CV joints it's possible, but why bother if the boot is split now and slinging grease out it will just do it again. You could grease them and install a new boot. Think they make a split boot for these cars.

definitively grease...from both sides..the passenger side just shoots out alot more. Im going to look into a split boot, that Im sure it must have a tear it them...not sure if they make a splt boot for the inner part of the axle

Since its the inner boots and depending on your expertise, it may just make since to replace the axles. The way the you say the car is stumbling its probably causing the grease to be expelled stronger (the trans yanking the axles) etc. And It probably was coming amount in a smaller amount before.



I would maybe try to add some grease to the old axles depending on the size of the tear..the stumbling probably caused the tears in the first place or made it worse..I wouldn't change the axles until the stumbling problem was fixed.

When was the last time you did a tune-up (plugs/wires/air filter) and cleaned the TB and MAF?

I will get under there and see how bad the rips are and try to add grease with a grease needle.

I will be doing the tune up this week.. I have cleaned the entire throttle body and tried 3 diff mafs..with no change.

I noticed this happens when the car gets warm and a trans wine accompanies the symptoms. I recorded it earlier IMG 0368 - YouTube
