Lucky SOB! I've been eyeballing the Shaftmasters DS for a while.

And no, you can't beat it for the cost. Not doubting the quality of other DS's but I can't see any reason to spend another $150 ($750 total) for another brand. I think the difference is just the mark-up vs going direct with the mfg, Shaftmasters in this case.

Oh, hell I wish I lived that close...that's just how far the DS plant is from where they build the Mustangs. I live just a couple hours away though, and I have considered taking a drive up to Michigan just to see what I can get directly through them.

So you installed the Steeda UCA, but did you adjust it correctly? Your symptoms sound exactly like your pinion angle is still off. It can take a few tries to get it set correctly. First you need to "phase" the angles in and then you can start adjustment. I will post some links for you that explain it really well if I can find the damn things. I would guess that you may need to lengthen the UCA a little bit to push the pumpkin up just a degree or two. Its really just trial and error to get it set. Just adjust 1 degree at a time or so and test drive it. I also agree with the others...you should have your drive shaft balanced just to be sure its ****.

Nice, thanks! Baby steps.

here is a decent link that explains what is going on with the drive shaft angles. Its a short read but should help you understand whats happening.

Thanks for the info, and unfortunately, I don't have the tools yet to do any of this myself anymore, but at least I'll have an idea if I can find a reliable mechanic...and there's not a reliable mustang place anywhere close. If anybody knows of some place good in Chicago, please let me know.

I would look at:

Confirm the wheels are balanced
Make sure DS is true. Use a good shop.
COnsider a warped rotor.
I doubt it is suspension related but it could be. Stock LCA's?

If you have a buddy with a floor jack, couple of jack stands, and a couple of big crescent wrenches for the jam nuts, you should be able to adjust it yourself man. Here are the instructions for your UCA...http://www.steeda.com/store/uploads/...ol-arm-1-1.pdf

Time to get your feet wet and do the work yourself ;-)

BMR LCAs Simon1, and thanks Phil...I had a 98 Cobra and worked on it myself all the time...been 10 years since I had it, and haven't touched one since...so these are kinda new, and I'm really looking forward to being able to toy with it when I get more time...I just want to make sure it's going to stay on the road safely.

My car had the same problem with 4.10 gears. Well what it was was the install and it only vibrated and made noise on decell. I had the gears re-done and all was good.
