Need advice: 2005 Mustang U-Joint question...

[Fentonite]

Any mechanics or Mustang owners...

My wife has an '05 Mustang (V6), with 50K miles. It developed a rotational tapping sound in the rear end. She took it to the dealer, who charged her $59 to diagnose the problem. Their "diagnosis" is that it might be the U-joint, but until they replace it, thet won't know if it might also be the differential. Problem is, they say they have to replace the entire driveshaft with the U-joint, as it's all one piece. They want $600-700 for the repair.

Does this seem right? Does anyone have any expience with this? I've replaced U-joints before (about 25 years ago), but never heard of needing to replace the driveshaft too.

Recommendations on a transmission shop?

Not impressed with Ford quality

I could be wrong, but I've never seen a u-joint that couldn't be replaced. Typically a $20 part. Like I said I could be wrong though.


*edit* Just spent 3 minutes on Google and found out that Ford is making their drive shafts with staked in u-joints and are not replaceable. On cars and trucks I guess. That sucks, I've broken many a u-joint whuile 4-wheeling. I hope other manufactures don't follow suit.

Oh, and read some more, Ford went back to serviceable u-joints in the 06 model year. You're one of the lucky ones I guess..

Well sh%#, that just rubs salt in it.

I also read that it's a real bi¥€# to replace the driveshaft.

Well, the problem has interested me enough to look around more on it and it looks like a replacement shaft is around $700 aftermarket anyways. If the repair shop is going to do the whole job for that much, sounds like it is reasonable.

Another note, I can't possible see how it would be difficult to replace a drive shaft. It should be 8 bolts on the shaft and possibly a skid plate, would have to see it though.

I would contact a driveshaft specialty shop. They may be able to service the ends of the shaft, and make it serviceable, provided its aluminum or steel.

you can get a rebuilt from any number of quality builders in the metro area. I had ford tell me the u-joints were "probably" the issues i was having that caused my transfer case to leak, $1K for the shaft + labor. I went to a place behind kings pawn in greeality who did a new shaft, and joints for $175.00 OTD. Labor was on me. Took about 20 min to remove and another 15 to install, torque to spec then off the stands and on the road. I knew the shaft was worn but did not resolve the problem tranny leak. That they quoted me another 1K P&L. I did a tailshaft bushing & seal, again my labor for $28.00

I acknowledge repair shops do have competent tech, tools and training to do the job. If i am unable to trouble shoot & repair i go to the pros.
HOWEVER, it seems now a days the emphasis has shifted away from true trouble shooting and gone to a replace parts until the problem is resolved. A lot of the old time tech (like me) were trained to figure it out then repair, or rebuild, not "guess" this might fix it.
YMMV

[Fentonite]

Yeah, I've found some driveshafts for a similar price. I just can't get my head around being unable to swap out a $30 part like I used to. Seems like somebody creative should've figured out how to replace the u-joints by now...

Thanks for your info

Sounds like job security to me I wold say take it to a more honest mechanic if you can't do the job yourself but its most likely just a u joint you will also feel a slight vibration when they go bad

Great info about the rebuilds. And I couldn't agree more about the change in estimates and diagnostics. We're losing true craftsmen in every trade.
