Ok, so after my struggle with replacing all the rear suspension bushing on my LX with AHC I thought I'd make a quick post.

First of all, don't do it. Unless you have a good press, don't try to do the bushings.

But... Like the true LX owner I soldered on thinking, sure, this is fine...

Bought a bushing press die kit off eBay, that came with a bunch of acme thread rods.
First pass, nothing, and I started with the pan hard bushing since they are the smallest. Yikes, ok let's try some heat. So with a LOT of heat I got the "press" moving with a big breaker bar.

Ok so the pan hard bar come out pretty easy, and the bushings came out without a huge fuss, let's do a lower control arm.

Read up here, some say raise same side, some say opposite side... Mine was definitely opposite side. And had to raise quite a bit. Lots of back and forth, raise, check, raise, check, raise, check, too far, lower, check, lower...

Get that sorted and put mad sweat, blood, and tears into the bushings, basically two nights of labor after work. Almost done, only uppers now...

Man, for the life of me I couldn't find the right combination of angles to get the uppers to pop free. And there was not anything solid about other results, even FSM is a little vague. What finally freed them up was full suspension droop under both rear wheels. And this is with AHC set to high.

In recap, there are plenty of great replacement upper and lower rear control arms out there. BUY THEM. And if anyone wants some stock control arms with new poly bushings, I'll make you a great deal.
 
You couldn't get the control arms off? Just put a pry bar between the arm and the bracket...
It was getting the bolts out, couldn't get the alignment right for them to come out. Wouldn't budge at all until I got the height just right

Just hammer them from the other side with a drift or something

You can also put a jack under the pinion flange and raise or lower. It will roll the alignment of the axle so they slide right out.

I usually drift them out, but most don't like the BFH approach that some of us use...

:rofl:

I've grown out of my BFH phase, that's why I have an LX not an LC 🤣

I just did mine yesterday. Actually swapped all the bushings with super pro busing set. I did not raise the vehicle and took off one side at a time. Except one upper all of them came out easy.

This is what I did to get them out, time consuming but got the job done. Drill, and sawzaa.

I also had trouble getting poly in due to lack of a wisegrip but kudos to you for pressing in bushings with sleeves without a press.

I did the super pro poly bushings as well, just did the first drive on them today, and man what a difference!

Yeah same here, the thud is gone and it drives so nice. I still have to do the trail arm which I will tackle next Saturday.
 
I actually think that it now has better braking and acceleration. Hard to say, but I think my teeth are whiter too

Thanks for this tip, I was having trouble getting the axle to "roll" backwards enough to get the bolts lined up for the upper arms (even with three cranked ratchet straps).
