Locker Install, Front DS Vibes, Front DS Worn, Problems, Problems, Problems...

Install a Powertrax Lock Right and Solid Diff Cover in my Dana30 this past Sunday. Great project, and another fun Jeeper came over to help. Great day all the way around.



After the install, I ended up with some front driveshaft vibes at about 65mph.

Removed driveshaft, took it to a local DS shop for balancing.

They said the slip joint was worn, so they couldn't balance it. The slip joint is pretty loose. I have 123K miles on my Jeep.
(there were already a couple of balancing weights on it, so it's possible the vibration was from the worn slip joint)

They wanted $350 or so to completely rebuild the DS.

Any suggestions? Seems like any used DS could have the same wear issue, so buying a used replacement would seem to be a bad idea. Or I could try to find another shop.

$350 seems outrageously expensive, and at that price, I'll live with the vibes. For comparison, they were asking $60-70 for just balancing, and $150 to shorten and balance a Cherokee shaft (for use in the rear).

Thanks!

Try a different driveline company. Tom woods makes them brand new for a little more than that.

Great suggestion...

Looks like a replacement OEM-style shaft from Tom Woods will be either $199 or $219

A CV joint would be a nice upgrade, but I'd rather spend the extra $$$ somewhere else.

From Tom Woods Webpage:
"Our drive shafts will use an upgraded heavier than stock tube, larger/stronger slip yoke & spline stub (S spline) and our “Gold Seal” universal joints is $189. The top of the line shaft with the longer travel slip & spline (XC OR XB spline, see sidebar at bottom of page) is $219.

If you have a non-selectable locking front differential and want the smoothest drive shaft, a CV type drive shaft is generally recommended. For the Double Cardan (CV) drive shaft we have two options available. With our S spline, the drive shaft is $269. With our XC or XB Spline, the drive shaft is $299. Installing a CV drive shaft will require changing the front out-put yoke on the transfer case to one that is compatible with both the transfer case and the drive shaft. We sell this yoke for $60."

Question #1 I would have, is did removing the driveshaft cure the vibration problem? You may just be starting to get into more than 1 problem.

Excellent point...I'll take it for a drive tonight to confirm.

Drove it without the front DS, and there wasn't any vibration...well, nothing but the normal Jeep vibrations, squeaks, squeals and rattles

I reinstalled the original DS and will run it until I want to spend $200 on a Tom Woods replacement. Thanks for the tips!
