Finally got the Ford (Actually Dana) alum drive shaft and had it installed. No more clunk from worn out center bearing (moving about 1/4 " in any direction. Smoother, quicker rev up, and no more vibration in the stick. This is what Ford should have used from the start.

Yep - I have the same thing and couldn’t agree more! Except about the vibration in the shifter, but that’s due to solid motor mounts, the MGW and Blowfish bracket[emoji6]

Huh, so the FRPP are actually Spicer units? I had no idea.

Thinking about getting one, is the Ford Performance Part # for this M-4602-MGTM ?

Have't had a chance to install yet, hopefully I will have it installed sometime in March. Work gets in the way some time.......

Can I install it without pinion issues if I have non adjustable OEM uca and lca?

I’m not sure about that. Is your car lowered, or at stock height? I believe it’s a direct bolt in replacement for the OEM 2-piece, but I’d like other forum members to weigh in.

It's lowered about an inch, roush springs and Bilstein b8hd.

you should have no issues with it, an inch is not that big of a deal in the grand scheme of things and Desmo is right, the vibration through the shifter is extreme, but it's not because of the driveshaft, as he stated, it's mostly the Blowfish shifter bracket, which is normal, and a great addition as it not only doubles as the shifter mount, but as a driveshaft loop as well.

I don't have the blowfish bracket, just the mgw.

understood, I was trying to explain the vibration, it's in the bracket, not the driveshaft or shifter.

Hello, I installed the FRPP driveshaft and am very impressed with the increased performance at VIR. However, have high speed, high rpm vibration issue. Most noticeable on back straight between 6500 to 6800 rpm, 5th gear, so high speed. Can feel it thru the floorboard, see the vibration in the rear view mirror. I’ve clocked the DS 180 degrees at the rear flange. No improvement. Spicer says clock it +90, then -90, then clock at front flange. I don’t want to keep doing this and road testing. Need a track to test each time. Is there a better way or solution? Someone here in other thread says Kelly at BMR ( he’s no longer there or I would call him) says to lower the transmission mount by 3/8” ( for lowered mustangs). Has anyone done this? Are 3/8” longer bolts required? Thanks for any insight you may be able to share. Pinion angle is correct.

SPDBOSS,

I still have the 2-piece stock driveshaft (for now) but I took the transmisison cross-member off to install the MGW shifter. The cross-member bolts are fairly long. I don't recall if the bolts go through captive nuts or tapped holes but you can take a look to see how far the bolt threads extend beyond the nuts/threaded holes. It is recommended that bolted connections to have 2 or 3 threads past the top of the nut. But, I don't think you have to be concerned about 3/8", particularly if you use a little blue Loctite to keep things snug. Torque for those bolts is modest, only 35 lb-ft for the (four) cross-member bolts.

HTH,

Chris

I recently installed a one piece DS (Ford Racing) and definitely get a low frequency hum type vibration at 135-145ish. At 150ish it got suddenly quiet, went away completely. FWIW. Maybe that's just the RPM at which it resonates.

This and a MGW shifter has been on my tops on my list. I'm sick of the clunkiness and 60-80 mph high frequency whine I get. I'm waiting to pull the trigger 'cause I figure it'll be easier to install the shifter if the DS is down. I'm lowered with Eibach Pro's, maybe 1.5" lowered in the rear. Hoping the pinion angle won't change. It's dialed in now.

Not to dissuade you but my 60-70mph whine is very pronounced with the addition of my MGW and the DS. Can’t attribute it to one or the other but after both going in, it’s loud.

I appreciate the heads up! Did you have any whine before you put in the DS and shifter? My driveline is stock now and it's bad. The car's only got 20K on it. I'm as sure as I can be that the noise is coming from the carrier bearing, it's not the tranny and I hope it's not the Torsen diff. I figure, even if it doesn't completely solve the noise, I'll still enjoy the benefits of the two upgrades.
