I should also clarify that I did replace the spherical bearings when I put in the rest of the poly bushings. In fact, I'm the guy who pioneered the replacement of those spherical bearings. Prior to my write-up here, people were replacing the whole carrier assembly in order to get those spherical bearings.

So, yeah, I'm not advocating putting poly in place of those spherical bearings, only in place of the OEM rubber bushings.

Scott, your writeup showing that it was possible to "press" out the bearings with the puller was great.. Anyone can go to a local Autozone, rent one of these badboys and switch out all of their bushings..

And Bill, when you place an order with Mario, it'll take about 2 weeks to receive since they're shipping from Austria.

Once you get the subframe down, a screwdriver and a 3lb sledge is all it took to take all the bushings out.. Might want to think about giving the entire assembly a good degrease/wash and then spraying it with an anti-rust enamel.. like por-15 or plasti-kote.

Will I need to take out all the bolts that connects the control/trailing arms to the hub to have access to the spherical bearings? I tried just taking out the bolt on the control arm #2 and tried lifting up the control arm but a bolt on the back of the hub is preventing it to lift all the way. I would really want to replace 1 of the the four spherical bushings before my trip back to nj w/out having to take the other ones apart- if possible. Any suggestions?

In this pic:

notice that the rear arm is between the puller and caliper, the trailing arm is not shown but is just hanging, while the front arm is still attached in its normal position.

That worked on both sides for the rear spherical bearing. I didn't get pics of the front bearing and I don't remember specifically how I did it but I do know that I didn't remove the arms completely.

It's quite likely that I used a prybar to help wedge the arm up out of the way.

I actually just got done replace one of the rear spherical bearing about an hr ago. Took about 2-3hrs of actual work time to get it done. The hardest part was putting the new one back in. I did not have to take anything else off besides the wheel and that one bolt for the bearing in case anyone is wondering.

ok bringing this back from the dead cause well i can .
i currently want to replace every bushing in my car starting with suspension then diff finally engine mounts now i get the logic behing using stock sphericals for arm links 1 and 2 in the rear but here is my question, for the rest of the rear and front suspension is poly ideal?
is there any where a complete list of all bushings on the car?
my cars is dd with weekend racing (soon i hope) so far its all tarmac. so my plan is as follow:
stock links 1 and 2 in the rear.
poly front inner and poly sway bar links and mounts.
im going to tein ha's so ignore strut tops etc.
what other bushing do i need? also oem or poly?
cheers guys trying to get my head around whats ideal for my situation

Another bump!

VERY interesting thread on this topic over on mr2oc from some competitive autocross folks...

Question raised from that thread: which bushings in our suspension are multi-axis bushings? (and thus, possibly not a good place to use poly)

I'm looking at toyodiy and I can't seem to find the diagrams for the spherical bearings in the knuckle.

Just to confirm - do new knuckles come with the bearings pressed in?

Thanks

They do.
Some smart guy worked out that a model of Supra uses the same bearing, and can be supplied separate (it has a part number).

The one SuperPro bushing you have on the rear carrier, which on is that called?

[Gary ST165]

the purple bushing in that picture is ^^^ the rear trailing arm

ok so each side has 6 bushings 3 inner and 3 outter...
which 2 (one side) do you replace with the toyota spherical bushings?
i know the trailing arm can be all poly. so there goes 2 out of the six for each side.

so of the four remaining bushings in the radius arms, which are poly and which are OEM?
would it be safe to assume the hub (out board) bushings are poly and the cradle/inboard are the OEM spherical?

The spherical bearings are on the hub side
