I'm fixin on ordering some new front sway bar bushings.

Rockauto lists bushings for a 1.72" bar and a 1.80" bar.

I slithered under the TB, and got the part number of the sway bar, 15167261. I went to Google and axed Google what the bushing size was. Got nothing.

So, I wrapped a slice of paper around the bar and made my marks. 5.5". I then used my TI85 and got 1.75".

Now how in the crap did I get a number other then 1.72 or 1.80? I went back and redid the measurement, 5.5". I redid the math, this time on a casio calculator. 1.75".

I don't want to get both sets and return the set that does not fit. I want to learn what I did wrong and how to get the right measurement.

So if anyone can sway me in the right direction I'd appreciate it.

5.5" circumference = 1.765" diameter. (Pi assumed to be 3.1416) So it's more close to the middle of 1.72" and 1.80" than your calculation, even.

I don't know the answer to the bar choice question, but somehow I didn't think you were too cheap to own a Harbor Freight digital caliper, Mr. Tech II. :raspberry:

Digital caliper, eh? I get by with my old school KD mic. Well, got by with it.:frown:

I think my work has one of those fancy digital thingys that go a bit bigger. I'll use that tomorrow and see what it says.

I believe, once you scrape off any rust, dirt and/or rust proofing, you'll be very close to the 1.72".

Also, the sway bar is slightly bigger than the hole in the bushing for a solid fit when you tighten the bracket bolts.

If it wasn't late I'd be scraping the bar right now and remeasuring. So tomorrows testing will include scraping and using a fancy digital thing. Thanks man!:hail:

Take the bushing out and look at it. When I did it was marked 44mm which is 1.73"

There are 2 sizes of front bars 44mm and 46mm.

44mm bar indicates you need a 1.72 bushing

46mm bar indicates you need a 1.80 bushing.

just jack the front up and remove the 2 bolts that hold the bushing in and remove bushing. No need to remove any other hardware. Replace and then do the other 1.

I did what you suggested and there it is, 44mm. Thanks!:hail:

Digital things aren't FANCY

You mean there isn't a robot inside measuring stuff?

After some super light scuffing with some choice emory cloth, the fancy mic read 1.73".

Good to see you found out which size bushing you need.

I was in the same boat like you, no info anywhere, just had to figure it out myself.

44mm = 1.73"

Both methods same result.

BTW nice matco socket:smile:

Just took my front bushing out and the size marking was worn off. I measured the ID and it was 44mm. Rockauto only has bushings with an ID of 1.34" and 1.42". Is that the size of the rear bar? FYI 2006 I6 TB 4x4

look at the rock auto listing for 2003 TB. looks like the photo is different. what do your bushings look like?

I think I read that they changed the anti-sway bar geometry along the way, so you should be careful

Bushings look similar to photo earlier in this thread. I'm just going to get the bushings at the local auto parts store. Returns will be much easier.

I just thought I'd ask this question since I'm going to change the front sway bar bushings today. Should I do this with the truck on my Roadie ramps or should I jack up the front and use jack stands and let the suspension hang? Does it make a difference or not? My guess is using stands but thought I'd ask...

As long as both front wheels are compressed or loose, the anti-sway bar will have no stress on it and you can safely take off the brackets. Folks who lift and support only one wheel at a time have a big surprise when they try to change one end link, for instance.

Thanks for quick reply :thumbsup:, my Roadie ramps it is then...
