DFW-area driveshaft repair?

I may need a U-joint. I have seen the references to shops in San Antonio and Portland, and several places selling units from Powertrain Industries; that offer rebuilt shafts.
Any recent updates on options for a new U-joint; particularly in the DFW area.
Don't want to go the full $340 route if I can avoid it.

Give David Poole a call at European Performance. If he can't do it, i'm pretty sure he would be able to recommend a place.
With best regards

Yeah, I've visited David before - pretty knowledgeable guy. Good suggestion; he might know a source.

Larry, I started to send you a msg. I remember your experience with the center bearing.
Mine has had a slight shudder when accelerating off in 2nd gear, only between 15-17 MPH. Done it for 5 years.
But, lately it seems to be getting worse; noticeble during each start, and really noticeable if accelerating up hill at the 15-17 MPH window.
It normally lasts only a couple of seconds, longer if going uphill. Shakes the car pretty good; feels to be driveshaft speed.
Smooth as silk at cruising speeds.
From the time I first noticed it, I have replaced the front flex, the center bearing, the tranny and dif mounts, and inspected and switched the rear axles L to R. I also tried repositioning the center bracket as you suggested; all with no improvement.
Last time I had the shaft out - several years ago - I definitely had the "detent" in the u joint. It wasn't too bad, but if it had been replaceable I definitely would have done it back then.

I'm gonna go back in and check everything; but since I replaced most of the stuff over the years with no change, I'm kinda assuming I just didn't hit the right part, and it's slowly getting worse. And the only part left I can think of is the U joint. The rear flex is original !!!! but it looks & feels fine.

One last caveat: last night I swear I felt the shudder in 3rd gear, at the same RPM as it's always occurred in 2nd. If that's the case, it's likely in the tranny or torque converter. Man, I hope not. But if it continues to deterioate, I guess I'll find the sneaky devil easier.

Ever heard of a non-lockup converter going out?

Since you've already tried the offset trick, I THINK that you are on the right track.

The MB driveshaft specialist that I've seen great work from is Beijer in Arizona. They won't do work for individuals, even part timers like myself. I got an MB shop to do the paperwork for a 10% fee.

Good luck with it,
