I have a 2002 4dr 4x4 blazer that I am looking to replace the sway bar bushings on. Perhaps someone can clarify the correct sizes I need. Rockauto lists 1 1/16, 1 3/16, 1 5/16, 1 1/4, 1 1/8, 28mm, 33mm.

I took a caliper to both the front and rear bars.

The front is ~1.36 - 1.4"
While the rear is ~ .91 - .93"

I called the dealer and they gave me PN 15010349 (33.5 mm) for the front and 15697706 (not sure on this size) for the rear. I think its a safe bet to say the 33.5 mm is what I need for the front. The back has me stumped though. Is there a better way to determine the correct bushing size? Are the bushing sizes based on "handling preference" or strictly by suspension option? As far as I know, I have standard suspension. BTW, what is "problem solver" in terms of sway bar links and bushings? Thanks in advance for the help.

 

*bump*

Nobody's changed their sway bar bushings or ran into size discrepancies?

 

I've changed sway bar bushings, but always just asked for the part for my blazer. The rear I got a poly kit from summit and the front I got a polly end link kit from Napa (I haven't done the bar to frame mount).

When you measured, did you measure right where the bushing wraps around the bar?

I think problem solver usually means that it's designed to last longer than a generic wearable part.

 

Still havent gotten around to changing these. I was under the car this morning changing my sway bar links and I realized I never did determine the correct size of the bushings. To answer your question, I did measure the bar right at the bushing with my calipers. I am still measuring 1.4" for the front (36mm) and .90" for rear (23mm). The only sizes listed that I can find for 4x4 are 33mm and 28mm. I guess I should assume these are the right sizes. Anyone have any thoughts?

 

I just did they sway bar delete... Found them to be more of an hassle then anything.

 

? /\

 

sway bars are useless... They get in the way of bigger tires...

 

??? Not in the slightest. For offroad only, I could see the point as they can limit articulation, but for on road... They are an important aspect of the vehicle, especially those with a higher center of gravity than stock. Unless you ALWAYS drive in a straight line...

As far as the original question. I suspect the sway bar diameter quoted by just about every parts store & dealer out there is not including the paint. The 33mm bushings should be what you need.

 

Actually, I never noticed a difference when I removed mine... But I was joking around, as saying everyone should be off road...lol
