Question about 1999 Mercury Grand Marquis

1 Answer

Grinding noise from rear of 1999 Grand Marquis

Car has about 80,000 miles and have noticed a "grinding" kind of noise from the rear of the car. This happens at low speeds when I am turning. It has been suggested that it is a problem with the differential, possibly ring and pinion gears, or bearings. I've been told it could cost up to $1,500 to fix the problem. Does any of this sound correct?

Doubt it very much
the only gears in action are the axle spider ( spur gears ) and they turn very slowly on turns
pinion and crown wheel, noise are growls and whines depending if accelerating or costing and makes no difference if turning or straight ahead That should save you $ $1500.00 for a diff center that costs only $450.00
indicates wheel bearings or brake pads ( linings ) worn out and the callipers rubbing on the rotor ( drum)
I would be checking at the wheels and wheel bearings for the problem

SOURCE: rear wheel bearings

First check the brakes on that side. You may be hearing the warning rivets on the brake lining. If it's good, You need to remove the axle and go to the machine shop and have a new bearing pressed on. The machine shop should only charge you about $20.00 to do this.

If you have the caliper and retaining rings off the park brake must be holding it. This vehicle has small parking brake shoes that apply to the inside of rotor hat. Try backing off the adjustment and tap the sides of the hat to free them up.

Identify cause of right rear wheel stuttering in turns (either direction) at low speed. No unusual noise.


Is your car a rear wheel drive? If so, the limited slip differential grease is low...if front wheel drive could be right rear strut/shock assembly is totally worn out...wheel bearing maybe, but usually makes a grinding noise...does applying the brakes affect this stuttering? Should be a free inspection at most quality repair shops...good that you notice this before it gets worse...

Wheel initally with start making a washing machine noise or grinding sound when doing sharp turns the opposite of the wheel side as the outer race will generally go bad first. You may also notice the rim heating up due to friction. Grinding at low speed or a growling sound would dictate an inspection.

Rear tire noise


How many miles on your 328? My son's car was making a grinding noise and our independent mechanic told me it was the rear differential. I assumed he was correct and bought a replacement. However, before I installed it, I noticed the outer 3/4" of his passenger side rear rotor was discolored and no longer shiny. His brake caliper was grinding the rotor! It was because the hub bearing was so badly worn. I replaced the bearing and all is well.

will try to assist you. did you have your clutch replaced professionally? if it's a popping or cracking sound when accelerating or turning, it's most likely a c.v. axle going bad. either on driver or passenger side in the front of the car right?if it is a bad c.v. axle it will pop and crack when you turn wheel from left to right at low r.p.m. if not this,you may have brake issues. either it's a grinding sound while accelerating or decellerating,as long as cars in motion the noise will persist.try tapping your brakes while in a parking lot in slow gear,hear something from driver front,have a passenger with the widow down on passenger side, hear it from front passenger side? the thing i go by is what i hear when i test drive to diagnose an issue with a vehicle is,axles?popping and cracking when turning the steering wheel from left to right at low speed. [axle problem] grinding,scraping sound? brake issues! hope this helps and thank you for choosing fixya.com and we are here for you 24/7 7days per week thank you!!!!

I get a grinding noise and slight vibrations that I can feel under my feet. This usually happens at low speeds, but has become more noticeable now at c. 30 mph.


You need wheel bearings.. One for sure maybe 2. Do you feel it in the steering wheel or floor? The floor usually means rear and the steering wheel usually means front. Hope this helps. It should change pitch when you drive left to right at a steady speed. :-) Cobra

Woouumm Woouumm noise


Check the right side engine mount ASAP!
Call the dealer and give them the VIN number.

There is a new TOYOTA part no. 123052-0D120 to address this problem.

The old design on 05 and 06 has the noise problem.

In order to pin point the problem I will need the VIN number.

Please post it and I will follow up on it.
