05 camber out range both rear wheels

[JGBuick]

Those bushings are for the REAR, lower control arms. MevoTech MK6580. It's already been verified that these bushings fit the REAR lower control arms.

Is this what you're going to use then? Does not seem you have much of a choice...

Yes, I already bought the bushings and have them in my possession. After countless hours of research that is the ONLY choice one has.

I forgot to mention but I have 4 of these bushings, i think because I bought them to do years ago but then said f that when I realized how involved it would be lol. Brand? not sure

Also I just went to see if I ordered on amazon and I saw this



Come to realize, I apparently bought both this AC delco AND the mevotech. I have both if someone wants to see comparison I guess LOL

Sorry for not responding earlier, I have been under the weather lately.
It seems some the information given are is for the car in question.
I have had the alignment checked and the camber is way out on both rear wheels.
The assessment was the bushings need replaced. A couple are working out of the of the sleeve(?). The only suitable replacement part that is available is the whole suspension arm assembly. This still available because it is used on the lucerne. However, it is pricey.
I still can't find ride height information that seems right.
The leveling system is working the same as it was when I bought the car and the tires then were not wearing out on the inside.
After a little more recovery time I am going to replace the arms and all of the rubber parts in the rear suspension.
Hopefully this will do away with this problem.
Thanks for the replies.

There was another post regarding the availability of the lower rear control arms. Most online GM parts listing are showing discontinued and out of stock, but you may want to confirm this and check with a GM dealer or it may require a different direction as getting the bushing themselves, just a FYI.

 

[BuickGirlFromMars]

your subframe in back is different than this, but that control arm is the same
just to visualize for you. I seem to recall I posted the AC delco part number for your bushings.

here it is is

Since you would be insane to lower the subframe and work on things without doing the mounts/isolators/ bushings etc there are the attachment bushings for the subframew, there are the sway bar bushing(make sure to get right diameter bushing), coil spring isolator top and bottom, shock mount, lateral links(check , good time),

Exhaust hangers(OE muffler or resonator may be a maintenance part?) if your exhaust was stainless factory, the muffler may be working still, maybe partially diminished. the resonators seem to like to rust because of their shape I think. in my opinion regardless of how you intend to handle or not handle the exhaust parts, the thing I would do is cut the exhaust before the resonator, after the cat in a straight piece. then make it easy. when you hang it and have to join it, use a exhaust clamp, copper gasket maker, some fiberglass casting,and mend the two parts LOL

Rear brake hoses would be wise at this time too
I may be forgetting something but then if your car is clean, do take the time to ensure all coatings are good and points of corrosion are stomped out 🙂

Trim Height Inspection​

Trim Height Measurements​

Trim height is a predetermined measurement relating to vehicle ride height. Incorrect trim heights can cause bottoming out over bumps, damage to the suspension components and symptoms similar to wheel alignment problems. Check the trim heights when diagnosing suspension concerns and before checking the wheel alignment.

Perform the following before measuring the trim heights:

1. Set the tire pressures to the pressure shown on the certification label. Refer to Vehicle Certification, Tire Placard, Anti-Theft, and Service Parts ID Label in General Information.
2. Check the fuel level. Add additional weight if necessary to simulate a full tank.
3. Ensure the rear compartment is empty except for the spare tire.
4. Ensure the vehicle is on a level surface, such as an alignment rack.
5. Close the doors.
6. Close the hood.
7. All dimensions are measured vertical to the ground. Trim heights should be within 13 mm (0.5 in) to be considered correct.

==========================================================================================

Z Height Measurement​

The Z height dimension measurement determines the proper ride height for the front end of the vehicle. There is no adjustment procedure. Repair may require replacement of suspension components.

1. Lift the front bumper of the vehicle up about 38 mm (1.5 in).
2. Gently remove your hands. Let the vehicle settle.
3. Repeat this operation for a total of 3 times.

4. ​

   Measure from the pivot bolt center line down to the lower corner of the lower ball joint in order to obtain the Z height measurement.
5. Push the front bumper of the vehicle down about 38 mm (1.5 in).
6. Gently remove your hands.
7. Allow the vehicle to settle into position.
8. Repeat the jouncing operation 2 more times for a total of 3 times.
9. Measure the Z dimension.
10. The true Z height dimension number is the average of the high and the low measurements. Refer to Trim Height Specifications.

==========================================================================================

D Height Measurement​

The D height dimension measurement determines the proper rear end ride height. There is no adjustment procedure. Repair may require replacement of suspension components.

1. With the vehicle on a flat surface, lift upward on the rear bumper 38 mm (1.5 in).
2. Gently remove your hands.
   Allow the vehicle to settle into position.
3. Repeat the jouncing operation 2 more times for a total of 3 times.

4. ​

   Measure from the front outboard control arm bolt center line to the bottom of the control arm wheel bearing and hub face in order to obtain the D height measurement.
5. Push the rear bumper downward to 38 mm (1.5 in).
6. Gently remove your hands.
   Allow the vehicle to settle into position.
7. Repeat the jouncing operation 2 more times for a total of 3 times.
8. Measure the D height dimension.
9. The true D height dimension number is the average of the high and the low measurements.
10. If these measurements are out of specifications, inspect for the following conditions:
    • Improper weight distribution
    • Collision damage
    • Worn or damaged suspension components

sounds like worn suspension
or improper ride control
if your car is not at trim height unloaded with the air system, then there is a problem with something thats for sure.
PICS?


here is one of the possible fixes depending on what you show us
View attachment 37580

Energy suspension parts.com Makes neoprene bushings for all cars. You need a $10 Walmart micrometer to take a couple measurements. 2 piece neoprene and a metal sleeve is included. Their website shows you how, quite simple really. I'm going this route. I may be able to install a new bolt with this 2 piece system with out lowering the sub frame, I'm investigating now.

Let us know how it goes. I would be really interested to see if this works out. According to the site, they only go up to 1996 on the Buick LeSabre's.

Only way I can see you dropping the rear control arms WITHOUT lowering the subframe would be to torch/cut the bolts out of the lower control arms. Then you would have to press out the OEM bushings, press in the new ones, and then the reinstall would be difficult, if not impossible, without dropping the subframe.
