It’s time…driveshaft replaced at 62k, rolling 135k. Chassis vibration is noticeable.

I’ve read most threads available thru search regarding aftermarket center support bearings, and compared the two most mentioned options.

So, maybe there are more opinions out there…that aren’t consolidated in those threads.

JXB Performance-$250ish

EPS-$399 ish

Would prefer the options that did not necessitate disconnecting of the shaft.

So, who’s BTDT…and what are your thoughts?

thanks in advance

i just installed the JXB. Install was supper easy with the carrier upgrade which didn’t require shaft disconnect. I recommend for sure. I think it was about $375

Done the EPS route on my last CTT- it is solid, but I'm going with the JXB on the next one. It appears to be better engineering and a more appealing design to boot.

Cheers,

I did the JXB on my Cayenne ('06 CTTS) recently and two Audi's (preventitive, Audi's CSB rarely go bad until at least 200k plus). If you are a decent mechanic the standard $250 is fine but it may be worth spending the extra $100 for their bracket if you don't have a lift (I've got a lift in my shop) and will be doing it on your back. They offer them in a Comfort and Sport hardness for the cushion material, I figured the Comfort still had to be stiffer than OEM so I went with that, less chance of harshness. I've only put a few hundred miles on it but it seems fine, including some triple digit speeds (For operational checks on a closed circuit of course)

I bought both and prefer the EPS over the JBX - it just feels a little more solid to me. Plus it came with a replacement guibo. Mine was getting cracks in the rubber.

I also did the Jimmy Fix on my old 08 GTS. It is still going strong for the current owner after 30K miles!

I installed the EPS version in April 2017 on our Cayenne S (957) and it has worked well.
Lots of miles and no issues thus far. I just used the support mount and did not use the supplied flex joint (donut) that comes with it as I did not need it as my Cardan shaft had been replaced by Porsche just a few years earlier

I installed the EPS version and have about 35k miles on it with no issues. Following install, I left all fasteners slightly loosened, dropped the vehicle down on the ground and drove gently around the block before final torquing down of everything to ensure all was settled in natural alignment.

95_993, you may just want to check the driveshaft alignment as the driveshaft will skew a little to the side due to Torque, Shop manual actually uses an elaborate alignment took to make sure it is perfectly straight. I used a laser level spinning in the vertical to do mine for the JXB install, when I installed a new drive shaft 40k ago I just eyed it.

I re-installed a stock one on my 2005 turbo about 20k miles ago. I filled and leveled the support bearing void on both sides with Permatex Ultra Grey vibration dampening silicone. It makes for a very solid bushing that still dampens vibration and was a bit cheaper. Drives great, no issues in 20k miles, and my turbo has a big tune on it with a good amount of mods. Its a decent alternative to the aftermarket ones I think.

I am reminded of my father's brief time in aerospace in the late 60s; the use of Permatex and other RTV products in making bushings for everything is both terrifying, but also proof it can be done.

Keep buying them driveshafts, guys. Jimi and I are laughing our asses off....

JBX in hand…$250 shipped. Should be this one, and done.

Then on to the rear wiper motor, gearbox, switch, etc…

Jimmy fix is way to go.
otherwise spray rubber with rustproofing oil every year to keep the rubber from drying up and destroying.

I have a new EPS unit for sale if you'd like it for 300 shipped just PM me

I did the EPS install this summer on my 2009 S with 115,000 miles.
Easy install especially with the video from PCA on YouTube.
Tricky part was greasing the bearing itself, which proved to be all dried out, so I am glad I followed the instructions.
