Unhappy Possible solution ???

I have an E.B. 4x4 1997 5.4L. I'm getting a gear rub, and chatter when turning deep right under torque.

I have changed the fluid in the rear and added L.S. additive, and still have the problem.

Does anyone have a idea as to what may be my problem? And about what to expect in repair?

Thanks a lot for your help on this...

Hi cobrah. Did you use ford friction modifyer or aftermarket L/S additive.If so drain and refill with the ford stuff and do several tight turns after warming the rear up.If still have problem you will need new clutches.Iam a ford tech and i had a few of these that i had to put new clutches in.And if doing it yourself make sure you soak the new clutches in ford friction mod before installing in rear.Hope this helps.

Red face Thx.

Thanks for the information you provided, yea I used the ford products ..so, I guess I'll get new clutches . Do you have a idea as to "how much"?

I will have to get the mechanic on this one to repair, I don't have enough tools for the job!

Thank-you again!

Ok..I will pass on a "quick fix " for the problem I had.. to you. In most cases you can tell what side the grind is coming from if you have a LS drive.

Place your veh. on a flat surface...jack up the grinding side only. Start your veh. place the shifter in drive and allow the tire to rotate at idle speed for five min. or so. Remain in the veh. at all times during this, as the opposite tire may grab traction allowing the veh to move forward.

Don't race the engine...idle only. I tried this and NO MORE GRIND!!!

I hope this helps those with a problem like I had, psdiesel much thx. to you as well!

Yeah you can do that like you said but you are wearing out the clutches from slipping them for a long period.But if all you are after is getting rid of the chatter around turns.that will work.

Talking reply ...



I understood that the gears that drive are made of some high carbonated fibers and are designed to give somewhat to wear.

Over a period of time the "race" becomes sharp and try's to crawl on top of the drive... "causing chattering". At idle speed the sharp points are worn down to eliminate the chatter and grind... a sort of resurfacing if you will.

I understand the logic behind the story ...I'm no mechanic and don't know if what the guy said "holds water or not".

I thought what the heck...give it a try .

The gears are not the cause of the chatter problem.There's actually clutch disc in the diff that a spring puts pressure on.When you go aroung a turn the clutches are allowed to slip giving you a smooth turn.But when you are in loose terrain and one tire is slipping the clutches apply more power to the wheel that has more traction.It is kind hard to explain without showing you.
