Lower Suspension Bushings
Hello All,
So I bought some lower suspension bushings for the lower control arm. I had to take it to a machine shop to get them pressed in. We ran into a problem and I do not know if I got the wrong bushings. I have a Moog part number K9178.
The problem is the bushing gets pressed into the control arm. The control arm shaft has splines that go into the bushings. This leads to the suspension not being able to move. Like the upper control arm the shaft moves freely up and down. Now my question is do I have the right part? What part of the suspension swivels. The shaft like the upper control arms or the bushings?
thanks

Just did my front suspension less than a year ago. Once the bushings are pressed onto the shaft and into the control arm the whole assembly is very hard to rotate. Hopefully the shop greased the bushing before pressing. I bolted the assembly onto the frame and was able to leverage them into position for springs and knuckles.
Good luck.

the splines are to hold grease
That puppy shoulda been greased up real good b4 pressing. Mine rotates fine, I could turn the lower shaft by hand. Mobil1 synthetic grease on everything before assembly.

I still dont understand sorry...here is a picture. I'm a visual person so..
In this picture you see the bushings. Fisrt question...Is this the right bushings? What confuses me is that the bushings have ridges and when pressed into the control arm it wont budge...
Which brings me to the control arm shaft it has splines that go into the bushings which wont let it turn either...
also that question mqqrked item...Does that washer have rubber on it?
Thanks

Those look like the right bushings. The bushings won't budge. The ridges keep them pressed in the arm real real tight. The control arm shaft is supposed to turn within the bushing. The splines are to hold grease as it's a tight fit. But it must turn, as that allows suspension movement.
IDK if the washer has rubber on it, it could just be rubber from the head of the bushing that shredded.

Thanks for the response...anyone know the part number for #22 in the picture?
Thanks again

Well, 8 years later and I have run into this exact same problem. Was charged a small fortune by a local machine shop to remove the shaft/old bushings and install new bushings.
After I picked them up, I noticed the control arm shafts were frozen inside the bushings. Absolutely would not budge.
To make matters worse, they had the bolt holes on the shafts oriented sideways instead of facing up.
I called and told them the shafts are supposed to be able to turn inside the bushing but they disagreed. Said the splines prevented it and all they could do is try to put it in their vice and try to turn it with holes facing up.
Anyone know of reliable machine and/or suspension shops around Phoenix area? Looks like I will have to get this job done at least twice.

spray some wd-40 between the bushing and the shaft, try to rotate the shaft. It must turn in order for the a-arm to move up and down once installed. Otherwise the installed spring rate will be much higher (stiffer).
Hopefully the shop didn't bend or distort anything in the press.
