can anyone snap a quick pic of the rear RX sway bar for me, I'm not sure where it's supposed to attach

It attaches to the trailing arms - two mounts on each arm.

goodly so far, that is similar to another vehicle I have... it has four attach brackets on the bar 2 end 2 mid

 

going to crawl under it again and look for bolt holes, (I may not have any)

 

where does the middle section of the bar tie into the car? kind of looks like it should be above and forward of the dif

The middle section of the bar ties into nothing - it mounts ONLY at two points on each trailing arm.

 

There are no bolt holes for the mounts - they are welded to the trailing arms. If you don't have the mounts you either have to make them, cut them from another car and weld them on, or swap the whole trailing arm.

wow, it's just a torsion bar? what's up with the 4 brackets that are keyed like the front bar, you know, they go into a slot and close back over the bar and bushing - it has to attach to the car somewhere - just like the front

 

hmmm... I'll get a crappy cell pic going

It does not attach to the car - it IS a sway bar, not a torsion bar.

 

A sway bar simply acts to keep the trailing arms LEVEL. It accomplishes this by attaching to two points on each arm (the brackets you are referring to). As the arms move in unison (both up or both down) the sway bar has no effect. If one moves up and the other down however, the bar resists this motion as you are trying to twist it. All sway bars work on the torsion principle - they resist being twisted and that action is used to keep the control arms at the same relative height to the body - IE: parallel to the horizontal line of the car's body.

 

Front bar's also have four mounts - the body mounts are simply there to keep the bar parallel to the body because there is only a single mount on the control arm - the arm being a strut control arm, does not move in-line with the sway bar arms - unlike the rear trailing arms that do. Thus it cannot act with the action of the sway bar ends and two of the mounts are moved to the car body.

tracking, yes, the front has 4 - just terminates differently, mis 'spoke' - it would help if I read your reply more closely, my fault

 

I had to get under there and flip the bar around a few times, yes, the 4 line up with the trailing arms - yes I have nothing to tie the bar's brackets to

 

savvy the principle behind the bar's opposing the motion

 

hmmm, this has the potential for diminishing return for effort, not crazy about the way it hangs under the dif and so near the exhaust

 

anyone got a pic of an RX trailing arm handy while I look on the net for some ideas?

 

GD?

this doesn't help me much, not sure what I'm looking for since I've never seen the mount (or an RX for that matter), second thought, I could get the trailing arms from the RX... but I wonder if their dimensions are the same as mine... could open up more problems

afterthought

GD, what if I drill and tap for the mount bolts and slot the trailing arms for the mount brackets off the bar - is this weakening the trailing arm and creating a stress point? will welding on the existing trailing arms weaken the material?

Just find yourself a set of rear trailing arms from any EA82 4wd that has a rear swaybar. I have a set but I put new bearings in them and might be making there way into my RX, depending on my STi rear subframe dilema

there's very little to work with over here :-\ only three cars in an 'official' yard 45 minutes south, or Spokane 90 mins north

 

thinking on what GD said, I can make some brackets - I'd just have to find someone to weld them to the trailing arms

 

hey, can you take a picture of your trailing arm so I can see what it is supposed to have?

I don't think it would weaken the trailing arm, but without some rubber bushings in there..... it wouldn't be quiet anyway. You could weld the bar right to the trailing arms it you didn't care about ever disassembling it
