Alum Driveshaft

[dstow13]

First I have a 2014 Mustang GT with some mods. Yesterday I installed a Driveshaft Shop Aluminum Driveshaft. At the same time I installed the Whiteline Transmission Mount Bushing and a BMR safety loop. After getting the car off the lift I did the driveshaft measurement. And it was within specs. Everything was torqued down and blue threadlocker as the instructions stated. Well my problem is that now when I'm accelerating I'm getting a vibration (when cruising I don't). It feels like it is coming from the center of the car. My next step is to remove the transmission mount and drive it again to see if the vibration goes away because I know a lot of people have complained about the transmission mount bushing causing a lot of vibration.

Do you guys think that would be the cause of the vibration? And when I remove the transmission mount bushing and the vibration is still present, what should be my next step?

Clock the DS 180*

There was a thread about that and if you drill a hole in it, it will help that. You need to do a search.

This.

It could be the mount, but my money is on the DS. I had the same issue.

Seems as though there are LOTS of issues with DSS driveshafts vibrating

Having a DSS shaft in my '14, I can comment as to NOT experiencing any issues.

I never said all the shafts were bad, but I definitely see many times more DSS problem threads than any other manufacturer

Didn't take it that way either, just giving a positive report on DSS products

I have the carbon fiber one, and I don't get any vibrations. Most of the time the people reporting the vibrations fix it by flipping the driveshaft 180*, like stkjock said.

Mine was a CF DSS and I had no issues on my '11, but when I swapped it into my Boss I had vibrations until I rotated it. I had no issues whatsoever with the Whiteline bushing.

I have a shaft master and no problems from 0-until.

No issues with my DSS aluminum DS. didn't have to rotate it either and measurements were dead on. I do have slight vibration from my trans mount. I installed it unmodified. I get a little vibration about 35-40mph in a high gear at low rpm. Not bad enough enough to bother me or make me want to remove it.

I'm new to the site and had just the opposite...........I put the Whiteline spacer in while still having the 2 piece driveshaft and had vibration at between 2000/3000 rpm. Then put in a Shaftmasters 1 piece driveline and had no more vibration.

Did you change the length of you UCA? With my DSS I had a slight vibe a low speeds. Adjusted the UCA by a small amount and perfect. I set my length at 3 5/8s if I remember correctly.

For the bushing? Interesting.

I had tons of issues with mine even with the proper uca length. I had to get it rebuilt twice and both times DSS told me that it did not appear to be anything that I did that caused the CV joint to fail. I think I had a bad driveshaft with too much run out.

I just see a far higher amount of threads with DSS problems than shaft masters or whomever else makes driveshafts.

Length is irrelevant. Pinion angle is the key parameter.

I tried telling my wife that very same thing...

Yes, IIRC you drill a 1" hole in the large middle section

thank god, I read that as drilling a hole in the driveshaft and thought the dude was mentally unstable giving out advice like that. hah
