Question about 2001 Mercury Grand Marquis

3 Answers

Vibrations in the drive train of 2001 Grand Marquis.

Between 40-50 mph there are vibrations coming from the drive shaft. Have replaced u-joints. Problem persists. Upon deseleration it is worse at 48mph. Touching the gas peddle to accelerate, temporarily stops the vibes. Release the pedal and it returns. It dampens out under 40 mph and somewhat less above 60mph.

    This sounds like a good solution however I would like another opinion. Can there be another possible cause.

Hi and welcome to FixYa,

Initially, your described problem often are the universal joints. replacing them should have resolved the issue. Since this is not the case, another possibility (among others) is the propeller shaft (drive shaft) itself has lost one or more of its balancers (or at least that's how they are called in my country). These balancers are metal weights strategically placed around the propeller shaft to even out its turning. Think of them as the corrective weights used when rims and wheels are balanced.

Good luck and Thank you for using FixYa. Happy Holidays.

    Of course, it is also possible (though very unlikely) that any of the yoke would no longer be true.

I have a vibration at 70 miles per hour


if the wheel alignment is faulty ( castor wobble ) at 70 mph there is no way that you can describe it as a vibration as it virtually rip the steering wheel out of your hands. If it is a torque converter problem then at around 3850-4025 rpm stationary there will be a vibration of the vehicle and engine The sort of vibration that you are experiencing at 70 mph will come from a drive line problem. If rear wheel drive then it could be faulty "U" joints, worn slip joint or failed rear engine mount
If front wheel drive it may be cv joints or bent drive shafts,wheel bearings or brake callipers not moving freely on the mounting bolts.

Replace the u joints and carrier bearings for a 92 GMC Sonoma and now has a vibrations


When you removed the drive shaft, did you properly mark the shaft where it comes apart at the carrier bearing? This joint telescopes and usually must be separated to get the carrier bearing on/off. If you reassemble the shaft 180 degrees out (most shafts can go back together two ways), you will throw the driveshaft out of balance. The vibrations will be felt from almost the instant you start moving. You will need to drop the shaft and reassemble the shaft back to its original position.

I have a bad vibration in overdrive around 50-55 mph on 2004 chevy avalanche


The first palce I would check is the drive shaft and universal joints. These will cause vibrations when they are about to go out. If there is any play at all in the universal joints they need replaced. Not a hard or expensive repair and like I said check them for play before you go any further.

Vibration in right front at high speed.have greese on hood in engine comparment on right side


Hi:
You should have your right drive axle inspected, especially the rubber CV joint boot. if it is split open , it is the most likely cause of the grease you found. Unfortunately, the damage to it is already done, and that is what the vibrations are most likely caused by a worn out CV joint. To fix or repair it, you need to replace the cv joint or drive axle assembly

98 gmc sonoma w 2 pc drive shaft 2wd noise from rear u joint and vibration at 40mph and up. have replaced u joints and carrier bearing. rear ball and socket were dry and rusty.


remove the rear shaft from a 1990 full size gmc van (g-van) make sure the one you select has the scew on sleeve at the front of the rear section of the shaft
this will be the right lenght
take the rear yolk off your old shaft cut of the ball socket now get the same u-joint your truck calls for and mount the rear yolk (the section of the shaft that bolts to your rear end) to the new shaft
this works ive done it
you eliminate 2 of the 4 u-joints and lighten up your shaft this releives strain on you tranny and rear end when these u-joints and ball bearings fail they cause the vibrations which ruin the rest of your drive train also you gain 10hp
i spent 300 bucks rebuilding the OEM shaft and got no where so for 25 bucks i did this
