Chrysler Repair: left front wheel noise and slipping, 1995 chrysler concorde, chrysler concorde


Question
I have a 1995 chrysler concorde.  It has just started making a grinding sound when braking from high speed.  Grinding gets louder as I slow down but does not change in speed/freq.  Does not always grind when braking.

I have also noticed that when I accelerate from a stop and turn to the right it feels like the front wheels are slipping ( I am not going fast enough to spin tires)almost like I am accelerating on ice.

Both of these issues started at the same time.

Thanks

Hi Hank,
I can't tell for sure what is wrong, but I would begin by taking a look at the constant velocity joint boots on either end of the drive shaft on the left side. These wear out and the rubber cracks, allowing the joint grease to leak out and dirt to get in. When the joints run dry of grease they tend to grind or thump when placed under stress (accelerating or braking) and they also tend to make noise when turning from the straight ahead track direction. All those activities place more stress on the joint. If the boots are torn you can either have the boot replaced if the joint hasn't been too badly damaged, or buy a new rebuilt half shaft with new joint and boots. You can save money by replacing the boots yourself and cleaning and adding new grease to the joint(s), but it requires a set ot tools and a torque wrench, jack stand, and a good instruction sheet. There are boots at both ends, thought the outer boot usually goes out first because it has to flex more than the inner boot. To see them well jack up the left front of the car and for safety put a jack stand under the frame, then look for the drive shaft that connects the transmission housing to the wheel housing and note the rubber boots with ridges. Check that the boots are not torn and that no grease has been flung up on the body or suspension in the vicinity of the boot which is the sign of a tear. You may see the boot itself to be torn.
If the boots look o.k. I would suggest that you remove a road wheel and check the thickness of the brake pads. You, may be hearing the warning sound built into the pads (at least the oem ones from the factory have these metallic 'fingers' that rub on the rotor) that alert you when the pads have reached a thinness that requires them to be replaced.
As for the slipping impression, I can't imagine what could be going on there unless the transmission is slipping at one of its several gear clutches. Maybe the impression will go away if you repair the other cause of noise.
I hope this is of some help.
