Aftermarket Sway Bar Fitment Issues (Progress, Perrin, etc)

I just put mine up on jacks as I've been hearing it quite a bit more over the past week or so, dunno why it's cropped back up more lately, maybe I was playing my music too loud for a few months. :lol:

 

I'm having the same issues and I have some rubbing up front too. My setup is stock suspension other than the bars, that includes bone stock endlinks. I've found up front any setting will rub, in the rear, same is true. If they didn't rub they'd actually do a nice job, but they're annoying as hell and as far as I'm concerned, over time could be a safety issue.

 

I'm really unimpressed at how far the front endlinks are smashed out to have to work with this bar, it's incredibly disheartening.

 

I'm taking my pix as soon as the camera recharges. I'll take picks with it on, then taking them off, washing them, and more pictures and putting the stockers back on. I will be in contact with Perrin...

 

BTW, I have the Perrin bars for reference.

SUBE555: Thank you for your post. Please take photos before you remove them from the car. It will be most helpful in determining the root cause of the interference. You mention something about the endlinks. Please detail those in the photos as well.

 

I can't stress enough that this is not a complaint that has been addressed to us prior to Mr. Hunter yesterday. We will work with each person or their dealer to get the problem addressed immediately.

 

Thanks again!

The ONLY photos I have seen regarding this bar fitment are from your e-mail yesterday and one from you through your dealer this morning. We don't have nay other photos period. There may have been a simple communication. MY question about the endlinks stemmed from his comment below:

Just trying to get all the info.

 

Thanks!

The ones that Peter sent are the ones Seth took. He took a wheel off to get a different angle that wasn't possible on the ground. Posted below:

I am going through my photos right now as I have taken about a dozen and a half on front, back, left, right to document the issues and rubbing on both front and rear bars.

 

To back up my credentials per my observations, I am a mechanical designer (with an associates degree) by trade with a defense contractor. My group consistently works with kinematics and motion studies thus my major complaints per motions of the bars, contact points, and tolerance stackups involved in rotating components with bolting tolerances as well as rubber/soft material bushings and other things I'm probably not thinking about.

 

Now my preparation for the investigation per the problem components, I made sure not to touch the dirt/debris in the area of the members as you could tell nothing was moved or changed at all recently and could more clearly see where bars were contacting. I did my best job with getting the best photo angles I could (including removing wheels.) A big note per the angle of the bar when not connected to the endlinks... THE CAR WAS ON JACK STANDS, no pressure was on the suspension at all. That significantly changes the angle of the bar in the position I had it, however it does not negate the fact of the geometry and that the bars were rubbing and touching.

 

The pictures are as follows...

As you can see, there is scuffing on the sway bar, in the same proximity, there is scuffing on the steering control rod also seen where dirt is missing. Also notice the high angle of incidence between the endlink, it's mount, and the sway bar. This is the Left-Front.

 

http://homepage.mac.com/futureofx/.Pictures/LGTW/PERRIN/2.jpgThis is the Right-Front endlink. Unfortuntely I didn't get a better picture on this corner, but it looks the same as the opposite side. You can still see some of the rubbing from the higher sheen on the steering control rod in this corner.

 

http://homepage.mac.com/futureofx/.Pictures/LGTW/PERRIN/3.jpgThis shows how close the suspension components are at the Left-Rear corner at full jounce. The least amount of contact appears to be in the middle position poer trying each of them.

 

http://homepage.mac.com/futureofx/.Pictures/LGTW/PERRIN/4.jpgHere is a closer view of that same corner.

 

http://homepage.mac.com/futureofx/.Pictures/LGTW/PERRIN/5.jpgThis is the Left-Rear endlink, note the heavy scoring on both the sway bar and suspension link. There is paint residue displaced on the suspension link.

 

http://homepage.mac.com/futureofx/.Pictures/LGTW/PERRIN/6.jpgRight-Rear endlink, note the extend of the contact, it's fairly significant over time. I believe less than 10k miles, mostly highway commuting.

 

http://homepage.mac.com/futureofx/.Pictures/LGTW/PERRIN/8.jpgThis is the Right-Rear endlink, notice the same scoring as the left rear has.

 

http://homepage.mac.com/futureofx/.Pictures/LGTW/PERRIN/9.jpgI also noticed there are some spots where the endlink is making slight contact with the suspension link as well, lesser than the sway but, but none-the-less it is contact that the stock setup isn't making. Shown is the Right-Rear corner.

 

The bars were removed last night just after I took these pictures, the tapping sounds are completely gone, all the suspension noises are essentially gone now. I can positively say it was from the sway bars, both front and rear.

 

Jeff Perrin please contact me again at my email address to deal with this. I will only deal with Jeff Perrin and Jeff Perrin alone.

Jeff @ Perrin - I got your voicemail tonight and would like to discuss my situation with you. What's the best time to reach you tomorrow? PM is fine. Seth (SUBE555) and I may call you together tomorrow.

I guess its my turn to post about the problem I've had with my Whiteline Sways, the rear one anyway. Front clunk I had turned out to be a loose endlink nut.

Anyhow, the bar is basically really loose and slides easily left to right. This was the case when installed sans grease and greased to the max. Here's the results:

 

The bar after some spirited driving:

What the bar was rubbing against:

And my face after my brake pedal went to the floor:eek::eek::eek:

 

I spoke to Sean @ Rallitek and nobody else has reported this problem. I'm hoping its just a fluke but I'm not sure I want to try another Whiteline bar. Might make the smart move and goto Cusco.

 

EDIT: This is on a sedan with an otherwise stock suspension.

so now cusco's are the only sways that fit the BL chassis without rubbing?

 

SUBE555 and I have BP/wagons and Perrin bars. It's not confirmed yet whether we have defective bars or whether there is a larger design issue. SCANS007 has a BL/sedan and Perrin - he is checking his for interference, as he has noise similar to ours.

 

It would be helpful if you list sedan or wagon, brand of sway bar, and whether you have stock suspension or any mods. I have Spec B Bilsteins with std. height springs - much stiffer than stock. SUBE555 has std. suspension, which is why I think he is having the issue on all corners. I need to check the righ rear on mine as well as the front.

I'd say it's an aftermarket bar. I certianly can't walk over to the subaru dealership and pick on up.. and it's not covered under manufacturer warranty.

;)

 

True but it's OEM and as such, it works. I wish I didn't sell mine to 'upgrade'. :(

Thank you SUBE555 for your pictures. That is very helpful! Also, the information about the other suspension mods is helpful as well. Just to confirm your suspension is at full droop on the jack stands not at loaded height? (This greatly affects how the bars will look in photos.)

 

As I mentioned via e-mail to Patagonian GT that Jeff has been in the loop during this entire online and telephone conversation. However, he would be happy to discuss the matter with both of you via phone, e-mail or forum. Kindly e-mail him at jeff@perrinperformance.com. (Please note that due to an extremely high volume of traffic it may be 1-2 days for responses from Jeff. For the most prompt service please e-mail me personally at adam@perrinperformance.com or tech@perrinperformance.com)

 

Thanks again.

Wow...all these problems with Whiteline made me put my car back up on the ramps last night to double check mine. No problems at all. Nothing hitting and left/right movement is maybe 1/4 inch. Are all these Whiteline problems the adjustable or fixed bar? Mine is (are...I have the front as well and no problems there either) the adjustable set on the rear setting.
