Question about Ford F-150

1 Answer

I am having problems with my ford F-150 4.9L and it has a vibration problem?

Well my ford truck is not a Nissan? Would this cause the vibration problem? Cause where the drive shaft goes into the Transmission it has some play in it? Cause i took it to a shop and they told me that it had a bad brass seal in it and that is what is causing the vibration so would that cause the vibration problem?

    Well i mean it has a bad brass bushing in the rear end of the Transmission so would that cause the vibration? Cause i have already put new bearings put in the rear end and i have already had new U joints press into the drive shaft and i already had the drive shaft checked out as well. And that is all good also there is no problem with the motor at all. So would that cause the problem with the vibration in the rear end of the Transmission?

    My Transmission guy told me that it could be the torque converter causing the vibration and he told me to put some lube guard in the Transmission and he said most people do not know about that and he said that lube guard is made for the torque converter and it would may stop the vibration and if it ain't the torque converter causing the vibration problem he said the brass bushing is bad and he will look at it and if it is bad he will fix it. But is he right about lube guard or have you every herd of it cause you can buy it at Midway Auto Parts in Greer S.C.?

Yes that will it will also cause the rear shaft seal to leak. This is common on Fords. You should do it or you will leak transmission fluid

    My Transmission guy told me that it also could be the torque converter causing the vibration and he told me to try this lube guard cause he said most people do not know about that. He said it was made for the torque converter and it may stop the vibration. But if it ain't the torque converter it could also be the brass bushing in the rear end of the Transmission and he will look at it and if it is bad he will fix it. So have you every herd of lube guard cause i have not and would it work if i get some of it and put it in the Transmission will it work or is it good for it?

Could be a u-joint. Check it by moving the drive shaft side to side, if no play in the u-joints then they are not bad. If you need to replace the drive shaft I would suggest you find one at a salvage yard versus paying that much for a new one.

SOURCE: Rear drive shaft seal leaking

Yes, but you will need to mark the yoke position and exact number of turns to remove the nut or you will change ring and pinion gear lash setting when re-installing it. You can use a large pipe wrench to hold the yoke still while tightening, or get a special tool made for that.

Another way is to loosen the motor mounts. Take off the oil pan. May have to jack up the engine or lift it up with a cherry picker to get the pan to clear the cross member. Then you should be able to remove the old seal and install a new one.

Have they replaced the harmonic balancer (vibration dampener) on the crankshaft. I wouldve also made sure that thier wasnt a motor or a transmission mount that was bad or even possibly a broken exhaust hanger allowing the exhaust to sit or rub on the chassis, hopefully they checked these things before installing a timing belt which usaually causes a noise rather then a vibration
Good luck

If cv joint is bad car has a lot of vibration, boots arent torn or leaking, but makes a humming noise. is this cv joint or something else?

cv joints should not click as that is the first indication of a failed unit
( going slow and changing direction produces a click,click is a cv joint)
wheel bearings should not be tight as that will produce a humming noise and will result in early failure
because the axle turns with the change of direction ,the distance from the pivot point to the transmission changes and so the shaft will move in and out of the transmission to compensate
take it to an accredited drive line specialist for a diagnosis

Check for a worn universal joint on the drive shaft going to the rear wheels.

Check your transmission fluid level. (Low level can cause vibration on acceleration.)

Check to see if your transmission filter needs changing.

Does it only vibrate under heavy acceleration?

I am still having vibration problems with my 93 ford F150 4.9L

This sounds crazy but I had it happen once. Have your wheels balanced. On my truck, I had a slight bend in one of my wheels. I never felt it at low speed but as I approached highway speeds, it could feel a vibration. I had everything checked out and it ended up being a slightly bent wheel.
I hope that helps.

I have a 2005 Nissan Pathfinder. I experience a vibration in the drivers seat that feels much like a massage chair vibration. It occurs only when I am in gear (drive or reverse) and with the brake...

Your motor mounts are either worn out or broken causing you to feel the vibration from the engine. Another possibility is that your exhaust pipe is touching the body somewhere.

Hm. I had an irritating vibration at highway speed with tires that came with my car. I had the balance checked and it was determined that there was an out of round tire. I replaced the tires, had them spin balanced, and the rims were perfect. After that, the vibration at highway speed went away.

Tires are the most common problem for vibration at various speeds.

Where did you buy your tires or have them spin balanced?
