Lower control arms Poly bushings replacement to polyurethane

On my 08 hatch I am having issues with vibration on braking. My rotrs and brakes are new. I got under the car and checked the suspension. I found that the drivers side rear control arm bushing was cracked so I replaced the whole arm. The passenger side is just starting to separate so I left that one alone.

The vibration lessened so I probably need to go ahead and replace the drivers side arm again. But I want to take a different approach.

Anyone here using these front rear control arms poly bushings? Whiteline 53528 or The PSB's 264( problem solving bushings ). They also have the front bushings.

To be completely honest, you need to replace both sides at the same time with the same product, otherwise you risk... well, a lot of suspension madness by replacing random bits and pieces with other random bits and pieces.

Meaning, if you replace one side bush with something totally different from another side, you're going to likely experience some weird deterioration and ride quality, along with likely strange differences in handling from one side to another.

Yeah. i figured i need to do the other side as well but if Im going to change it out im going to go with poly. Which oneof these I am not sure. Probably the cheaper of the two.

I went ahead and ordered my items to perform the polyurethane upgrades to the suspension. I am doing poly all aroun don the control arms plus I just put in poly bushes on the sway bar.

I went with the PSB 264 for the lower rear and went with the WhiteLine W53286 for the lower front bushings. Also upgrading the ball joint to a Moog Greaseable K500209. This setup cost me a total of $145.52. I am doing all the labor myself since I have a press and all.








At the same time I am installing a new drivers side Transmission mount ( filled partially with window weld ) and a center motor mount but doing the Electric Focus type








I have one stock arm for the drivers side that I saved and already removed the old bushes from so that will save me some time on installation. My 20 Ton Harbor freight press cam ein really handy. Im glad I bought one. Ive done a few paying jobs on it so it has paid for itself. Can t his be done without a press? Sure. But will take a long time.






I should be done this upcoming weekend so I will take some pics of the arms and post here once done.

Parts came in. Here is a shot of the rebuilt drivers side control arm.




Bushings pressed in easily. Ball joint took all of a minute to press in using my press. Will get installed over the weekend.


EDIT...............I corrected the rear mount. I know that it is backwards in this pic. Sorry about that.

How are the rebuilt arms working out ? Did it solve your vibration issue ?
Was looking at new Moog lca assys but this might be better and about the same price.

I installed the drivers side this weekend. I didnt have time to do the passenger side but planning on doing it next weekend.

I also had to do a transmission mount so I knocked them both out at the same time since the transmission needs to be lifted up a tiny bit to get one of the bolts out.

So far so good. I can tell the steering is a bit stiffer and with that you get more road feedback. Once I get the passenger side done I will update and give a review. My Vibration issue is still there but thats because the passenger side rear bushing is bad.

For the money I think this is a great upgrade. Just takes a little bit of work to do it. Where in TX are you at ?

IMPORTANT SAFETY UPDATE



Hey guys. One very important and very critical safety related thing was left out of the installation video on the youtube for the rear bushings is that the rear housings have to be swapped over from the left side of the car to the right side of the car. If you don't then the housing wont have the curled over edge to prevent the bushing from slipping / backing out of the housing since there is nothing there to capture it while driving.

I just went and looked at my drivers side arm which I just did this past weekend and it is almost half way backed out !I already posted t his info on youtube in the comments section of the video. We shall see how PSB responds.



If you plan on doing this bushing install on your car you have to do both sides at same time and swap rear housings over from side to side.

Wow scary but good you caught it. Bushings do seem to slip into the housings pretty easily so makes sense to swap them around.
I am going to try this. Going with the Whiteline rear bushings instead of the PSB, like the idea of pressing in the shell.
Also doing the Moog joints. thanks for the tip. End product is superior to the aftermarket arms assemblys out there imho.
located in Plano.
thanks again for posting this up !

I finally got done with these LCA rebuilds. Got the issue with the control arm housings squared away. PSB has never run into this issue apparently. They didn't know how to respond to my situation even when I asked them if my solution would work. Guess they didn't want to say yes and something happen.

So again...........these PSB 264 bushings have to be installed with the housings for drivers and passenger side swapped over so the captive end of the housing faces the rear of the car.



I also opted to spray some of this on the bushings as a lubricant when pressing them into the housing plus it will lock them into place when dried as a precaution. Video does it with just a little lube but I wanted to make sure they dont shift at all.




One more tip.......if you mess up one of the long bolts for the rear housing to frame mount it is a M12 x 1.25 x 75mm. One of mine got snagged and it messed up a thread so it would go on right. I couldnt source one this weekend so oI wound up going to a junked out Honda Civic and took one of the suspension bolts that fit perfect.


The car does feel more responsive now in the steering. My vibration issue upon moderate breaking at about 45-50 MPH is gone now. Time for an alignment and tire rotation.

Thank you to those that offered advice and encouragement.
