#39 of 51 2003 LeSabre Noise and Vibration
Dec 06, 2012 (11:43 am)
I have two issues; don't know if they're related.
2003 Buick LeSabre Custom
1. I have a grinding or moaning sound in the front end, when driving about 30-50 mph. Even a slight turn to the right, stops the sound. Outside this speed range, the noise is greatly reduced or gone. Two people suggested it is likely a CV joint/axel. I was thinking it might be a wheel hub.
2. I get lots of vibration when braking. Pads and rotors were changed out a little over a year ago, and rotors donít look worn down.
What do you think? Thanks in advance for your help.

The moaning could be wheel bearing. If you turn left on a curve, the sound should get stronger, rougher, louder. Then you turn right on a curve, and the load is taken off that right wheel, and the noise is almost gone. My second bearing, a replacement, gave those same symptoms a few weeks back. No play in bearing for wobble nor any in and out play.
GM's spec on in-out play is .05 inch. That's not the wobble that most people like to test, it's straight in and out.

Sorry; front rotors were changed a little over a year ago. None of the four look worn down.
I jacked up the front, and had very little wobble on both sides, but no discernible in-out play.
Here are some pictures I took, showing how greasy the left (driver) side is. The right side is free of grease and oil. Maybe this is an indication of something.

Well, I guess the pictures didn't load, even though they showed up in the preview. Anyway, the left side is quite greasy throughout the whole axle area, both on the axle, and on surrounding components.
I'll try the pictures again.

Pictures have to be hosted on another website, such as photobucket.com. Then you link to it there with the address given by photobucket.com with your picture.
You paste that address into the post here, select the whole thing, and click on the IMG button in the row of buttons down below the post composing box.

Yep, that's what I did the first two times. The pics showed up in the preview, but not in the final posts. Ended up just posting the links.

It's hard to place where that is and what's above it for me. My thoughts are that the material looks gooey, not just oil leaking from the seal there? If it were, it would be fresher and liquid in appearance.
The coolant can leak from the bypass pipes for the heater on the side with the water pump. That coolant mixed with oil seeping down from the valve covers which can develope seeps may be mixing to give that gooey look.
You also can have oil coming from the oil pressure sensor above the oil filter. Some have trouble with that giving a 130 lb. reading as it fails and some get a seep through the plastic part of the unit.
You need to wipe everything clean and start over watching where the material comes from. Usually it's gravity bringing it from higher up.
I've read that there's a leak detection powder to spray on the area and then the new oil tracking down shows up really well. And there's an ultraviolet additive for the oil and with a cheap LED ultraviolet light, you can see where the new oil is coming from.
#47 of 51 Rear shocks on 2004 Lesabre Ltd
Oct 28, 2013 (6:16 am)
Getting ready to replace the rear shocks on my '04 Lesabre, and after doing some reading ordered the Monroe MA822 Max-Air shocks. The job looks relatively simple (even for a DIY such as yours truly), but I've read some conflicting info regarding whether my Lesabre has a threaded or clamp-on air hose connector for the air leveling system, and thus whether I need an adapter kit on hand before I start the job. My initial interpretation is that I *won't* need any adapter, but I'm just not sure. Can someone advise?
Figured I'd ask here before I get started and find out I'm short an essential part
Thanks in advance.

Just wiggle to loosen the old clampon plastic is what I had to do.
Also, do not let the left wheel drop completely. The rod for the height adjuster is on the suspension part; letting the arm fall free when taking the shock off overextends the sensor that it connects to.
