Rear suspension continuing..
 
Just replaced pillow ball bushings. With this instructions http://www.clubrx.org/default.asp?id...ntent=32&mnu=5

it took me little less then 4 hours. Including cleaning components and going slowly. I didn't use impact to assemble suspension, just to take it out.

Clunks gone. But I still have some play and it looks like toe links.

Have few questions:
Car has 72k on a body

1. Pillow ball at the lower arm(where 2 pillow balls go) to body connection seem to be loose but no play. Is it common replacement item? It's big pillow ball.
2. Toe links. Are bushing serviceable? How much they go for? I don't want aftermarket.
3. Is there anything else in a rear that might require attention?

Everything else seems to be solid in a rear.

No impact? Damn....that has gotta suck.
I have an electric impact...but it is the cheap one from Harbor Freight. I've been told that it doesn't produce enough torque to remove/pop the lug nuts, so I've been hesitant to use it on removing suspension components.

Sorry I can't answer your questions, but good luck. Will keep an eye on this thread as it has useful info.

What I said I used impact to disassemble everything and to press in new bushings. But I used regular wrench when assembling suspension together as impact got to much power. I like to use torque wrenches anyway...

Quick search revealed that toe link bushings go for $55ea.

Longtitudal arms (spell?) have 1 bushing and they not replaceable.

It seems that I need only toe link bushings and maybe bigger pillow balls for lower arms where they mount to subframe. Rubber bushings seem to be good.

The toe links are bushing on the small end and a combination pillowball and bushing on the large end. Both are serviceable, and tend to ride better and last longer than aftermarket.

I have a set of new mazda toe link bushings for sale, pm me for info.

The trailing arm has a bushing in front that can go bad. Check to see that this bushing is secure.

The trailing arms, toe links, and pillowballs are the big items in the suspension. Sort of related but worth checking out is the differential mount bushings. If these are torn or leaking the fluid filling, they should be changed.

On related note.. When I drive steady and let of gas/accelerate I get movement in driveline (shift stick moves)

Is it somewhat normal or some other bushings responsible for that? It's not bad to the point where it bangs, but I can feel it.

Aren't the toe links pillow ball on the small end, and combo PB & bushing on the big end?

Sorry, you're right. I wrote that out wrong.

Or motor mounts or diff mounts.

katit 03-29-07 02:35 PM

So, you say there should be absolutely NO movement/slack in drivetrain?

That isn't what people are saying.

Large movements often point to worn diff bushings b/c it allows more driveline twist. Worn motor mounts will also allow more drivetrain twist but you'll feel and see the motor shaking and vibrating if the motor mounts are worn.

katit 03-29-07 03:14 PM

Like I said I can't say something really bad. My other car has similar driveline slack. Probably need to find nice-nice FD and see how it drives to compare.

dgeesaman 03-29-07 05:09 PM

If you don't have your hand on the shifter and you see it move more than a fraction of an inch (which isn't all that noticeable) I'd say you should look for excessive play in the diff or motor mounts or PPF.

Yes, driveline windup and gear play is normal with all cars, but it won't cause the shifter to move left/right as you load or unload it. I think folks with bad mounts or ppfs notice the shift knob moving an inch or more from the looseness.

I feel it when I have my palm on a shifter, but it's alsmost invisible. Anyway, will check stuff when car will be on a lift next time

Sold

Another question about trailing arm bushings. Those looks worn also. From searching here I figured that Mazda don't sell those bushings. So, I have few choices:

1. Mazdaspeed bushings
2. Nylon bushings
3. Aftermarket arms

I prefer to stay with #1. Anybody know where to buy them? All posts about buying them were from 2005..
