Near the endlink but not on a bend.

 

ah, I ask that you measure again near the center of the bar and specifically near the sway bar bushing, as there are slight variations in teh diameter due to bending.

 

I'll gladly do that once all this water dries up.

EDIT. I did measure again (see orginal post)

 

I tried going through Energy Suspension and Autozone for the bushings, but gave up. ES evidently doesn't sell directly to the public and Autozone's search function is tedious at best.

I found the parts easily at Summit Racing, though. In case anyone else is looking for these, the URLs are...

Front Bushings for 1 1/16 - http://www.summitracing.com/search/?...=9-5162R&dds=1

Rear Bushings for 9/16 - http://www.summitracing.com/search/?...=9-5153R&dds=1

 

ES has a public catalog through, which you can use to get part numbers...

 

Yep, and then go to the local Autozone and pick them up. I wish I would have thought about that before I ordered them. I would have had the parts in my hand rather than waiting for them on backorder. (Not really patiently either).

Oh well, live and learn.

<edit> Update - I replaced the front bushings when they came in, but the rear ones went backorder again. They finally arrived and I've swapped them out. The rear bushings made a bigger difference than the front ones. That seems backwards, since the rear swaybar has such a small diameter. </edit>

 

Did any one finally get the first gen (1990) sway bar diameters and / or part numbers?

 

Did any one get the part numbers for gen. 1(1990) Ls400 sway bar bushings from energy suspension yet?

 

I know this thread is quite old, so not sure you are still on here, but I have a couple of questions regarding your bushing replacement project. Those rear bushings do not appear to have a slice in them, to get them around the sway bar and according to someone I have been speaking to at Energy Suspension, that is the case on the rear ones. Did you slice them yourself, on the flat side, in order to make them work, without having to remove the entire sway bar? I know the front ones do have a slice, for this purpose. Also, did you ever replace your strut rod bushings? If so, what is your opinion on poly versus stock? I have seen other threads that said the poly ones make the ride quality much more rough. I am trying to keep my nice smooth ride, but want the stiffer sway bar bushings, to prevent the car from leaning so bad when if I decide to corner it hard. So, I am all in on the poly sway bar bushings, but not sure that is the best route to go on the strut rod bushings. Your thoughts?
