Lol well I've had them since they first came out, included some hot sticky 80+ days before it got chilly and didn't notice the noise then, but we do have more humidity so maybe the extra moisture in the air lubricated it lol

Damn, this gives me hope that it is fixable, ive played with em quite a bit and think i can fix the front washers pucks to stop the diff from coming back the 1/5 inch or whatever amount with wielding but im spending too much time/effort on a $50 part. But im open to suggestions, Kelly at BMR told me he is going to help me out so hopefully we get this fixed.

Haha I will prolly swap them out for the actual bushings eventually, figured while I'm NA the lock outs will be fine but once I go FI I will go with the full blown thing

I myself have been experiencing the noises as well, like a metal on metal clink/clunk noise when decelerating back down to 1st gear or sometimes accelerating from 1st gear at a stop light.

I bet yours is doing exactly what mine was doing ,it really did it at low speeds and only got worse the longer of a drive I would do. I switched it out for Steeda's rubber black diff kit. After seeing their design and its obvious BMR in this case was plain and simply beat , after driving on the rubber 90 durometer pieces from steeda i get 99% less noise from NVH , 0% metal on metal noise , and overall same performance, I was skeptic of how this would do, after seeing the pieces and testing it....STEEDA TO THE RESCUE, here is why we were getting that noise,

You can clearly see the BMR piece rubbing metal, only a little bit, but enough, the Steeda piece is solid, like a rock, after you insert the metal cylinder in the new rubber its a brick , my wheel hop is 99.9% gone still and now my GF thinks i took my car back down to stock, no NVH, no metal rubbing.

Lol, it is always important to get your GF thinking that your car is stock. My wife still thinks that I have a loose belt...doesn't realize that I have a Whipple.

You can see how their pieces also have metal on metal rubbing clearly in the picture, they have many great products , wish they could tell us when a mistake was made in their own design or at least a warning. BK054 performs well but is not good for $40,000 car.

ok i need to take some serious notes if you are able to hide a whipple lol, i think my gf would know not all mustangs are rocket ships lmao

 

[FivepointOHYEAH]

but then again when we first met she had a 2006 Porsche Cayenne and honestly thought her V6 non turbo would beat a 'generic' 'mustang' lol she even sat in my car and felt the acceleration, absolutely not even a race. She couldnt believe how much slower it was, i even google her 60 time 7 and she denied all facts till the race. So maybe i can hide a whipple.

In that case, yes, the Poly in your pic should be much thicker.

I would not call it a mistake - I would call it a trade off.

I am not sure how many times I can post why we chose the thinner pucks for this specific application, but here is just an example of why we choose specific designs.

All 3 are from different cars - the bolt that isn't broken is, well, you go it. The thin lockout design.

I DO have some other designs I am still testing, like I have mentioned several times on this forum.

If anyone is unhappy with their kit, then I will assist them in any way I can.

We have shipped over 400 of these kits out with about 3-4 issues thus far. ;)



Enjoy your new parts! That Poly should be much more comfortable than the aluminum.
:cheers:

^ The above pics are all from VERY high powered cars that race.

We have to consider these cars when offering our components, because they are hardest on parts. Therefore, if we can make the parts work on these, the lower power street cars should not have any issues.

Im sharing my experience with others and I think others will find this information helpful.

This lockout is not as good as its competitors , your full kits are probably hands down better but thats probably for the the make your own Cobra Jet crowd. I dont see why bolts were snapping even with all that power being put down. Seems like that something else would brake first.

Personally I think metal on metal rubbing that is audible is a design flaw, as well as scratched up metal around my diff mounts now, but if you are aware and consumers are ok with that for 3-4 people who had problems then thats just the design.

I would for this product choose Steeda's kit. You cant win em all.

People are bending and breaking the OEM Bolts with OEM Bushings.

The fact of the matter is, the M14 bolts in shear was NOT a good design from Ford, for mounting the diff in terms of performance applications that make big power. Of course, that is not Ford's problem - as the system works as it was designed to.

And yes, you are right. Other parts can/will break first. Ever wonder why Ford put a cast iron Diff Housing in the Manual Trans cars, but an Aluminum Diff Housing in the Auto cars?

In this case, you were better off with the Steeda pucks. They are not lockouts like the BMR pucks, but they will help stiffen up the diff mounts. And yes, any sort of research would have told you that there is increased NVH with the BMR diff lockouts.

you didnt read the thread...I can live with NVH, that WAS NOT the issue.
