east side Portland Alignment Shop Recommendations

I just got my 73 on the road and took it on a good camping trip. Everything went great but and it pulls to the right when I let up off the throttle Also the steering doesn't return to center perfectly. The steering system is mostly rebuilt and has hardly any play in it. So, I think I should take to a good alignment shop for their opinoin, but since George's Alignment out in Gresham closed up, I don't know of any trusted shops on the east side. Any recommendations would be great. I am wondering if my c bushings are not in correcly or if they are the wrong degree. Any advice would be great.

Can't help with the local stuff, but whoever you use make sure they not only read the settings for all aspects (even the ones they can't adjust normally) but give you a printout for future reference too. And so you don't have to remember all that stuff later!
Lots of places just tell people these days that they don't need their camber and caster readings since they're not adjustable. Hogwash! Get the info.

What else have you done? Is it lifted? What mods did you do to the steering?
If you have one of the aftermarket fully adjustable steering setups, is the tie-rod oriented properly? Did you install a drop bracket and pitman arm?
What about centering the box before you did any installs?

Unfortunately, no matter how well you have your EB fine-tuned, they rarely exhibit very good return-to-center manners. It's just not in the cards sometimes. Especially with different size tires and wheels than stock.
More positive caster can help sometimes, but it rarely fixes it completely.

Good luck.

Ditto on Georges closing up.
He knew about Dana 30s , 44s , C bushings ,TRO, and Chev 3/4 ton TREs.
Does your Bronco have a locker in the back? Have you tried swapping tires back to front and vice versa.

Sorry for the slow response to your questions about my bronco. I did take it to an alignment shop. They didn't seem to know much about broncos, but they did align it and give me a printout of the results. It seems that my castor is basically 0 on both sides. So, I am going to put in 7 degree C bushings and see if that doesn't help (I might even be able to improve my driverside bronco lean while I'm at it). To answer your other question, I do have a locker, but I don't know what it is (it was put in by the previous owner and no info was given). I do have a lot of slop in the rear end, so I might be opening it up in the not too distant future. For now, I'm going to try new C bushings and see if that doesn't improve things. Also, I haven't tried swapping tires. I will try that as well. Thanks for the ideas.

When you get the old bushings out, see if you can read the imprint on the inside still, that says what degree offset they are now. If you have 4's in there now, you should end up with 3° positive, which is passably decent in many cases.

What were your camber readings?

My camber is .6 on the left and .2 on the right. I will definitely look at what degree my curreunt bushings are. I am hoping to have time time to swap out the c bushings this week.

Welll, I installed new 7 degreee c bushings, and they definitely improved the steering (my lean has also gone away). My old c bushings were either 4 or 2 gegree I'm guessing. I couldn't find any marking on them. Thanks for the help. It steers the best it ever has!

I had the same experience going from 2 * to 7* - big improvement !

Well, "officieally" it's 1° to 2° positive. But that sucks on an EB!

The factory specs seem to drive ok, but almost always lead to excessive wear on the tires. Especially it seems on the outside of the passenger side.

We've been finding a reading under 1 degree is best. Somewhere between a half and three-quarters of a degree-positive is good.

Of course, it all depends (like most things) on the tire and wheel and suspension and steering combination. But for what most of us run, those numbers seem to work well.

We swapped 79 D44 disk ends onto a 74 drum Bronco axle. You can see them pulled in at the top but man it runs fine at 65.

Interesting. To get all the way from positive camber to negative camber, one would think that something ain't right!
But, negative is not necessarily a negative for handling, as that's what performance tuners do for autocross and such. But the same wear issues apply whether negative or positive. Too much and you get tire wear. In your case on the inside.

Luckily having toe-in in conjunction with negative camber might negate some of the wear equation, but I have no real clue about that. Just spitballing.

Have fun though. Sounds like it drives ok for now. Maybe still have it checked on a rack so you know exactly where you sit. Using camber shims or ball-joint eccentrics, or both, can fix just about any "normal" variation.

Sucking the Jack juice earlier. OUT at the top!

Ahh, very common then. Sometimes it's just a visual thing, other times it's a fact that it's more or less than what was installed previously.
Even the stock 2 degree setting makes the fact of the tires out at the top VERY visible. But while it might be within factory specs, you can still benefit from reducing it some.

Always make sure any alignment guy gives you the full readout. At least three different Bronco owners had to go back to the alignment shop and get the printout the guy should have provided in the first place. The usual excuse seems to be that: "you don't need those specifications since you can't adjust them anyway" or some such claptrap!

we're still having the occasional death wobble but I think I'm narrowing it down.
I feel the need to keep replying since you are closing it on my post totals!

You're safe for awhile yet. But it's always good to hear what mishaps are going on in your Bronco world!

You've probably read plenty of my comments on Death Wobbles, but it seems like it's been awhile since anyone has had one.
If it's indeed a Death Wobble, even though it happens occasionally (which is very normal) then even though loose components and off-kilter alignment settings can aggravate it, I still say the bottom line culprit is always a tire or tires.

Have you rotated any of the tires yet? If so did it change the attitude or frequency of the wobble?
What other things have you done? And have any of them had any effect on the wobble?

Let's get this conversation going man! Gotta get some real energy here on the site. Been awhile since we've had a nice juicy DW hunt!

I bet that Bronco death wobbles just thinking Tom might take er for a spin

Thanks Art.
Matthew had it happen like 5 times in the same 2 mile stretch. The steering box is off a Nissan and the pinion nut had come loose just a hair. Tightening the livin snot out of that seemed to help as did tightening the snot out of the lower trac bar nut.

They usually do help for awhile, but if it can be repeated, especially over the same stretch of road, then it's sounding even more like a tire-induced wobble. Especially if you can get it to go off when hitting a certain or road irregularity at just the right speed.

What seems to bring it on exactly? And now that it's reduced a bit, is there still a bit of a wobble that can be felt, but that just doesn't quite reach the frequency of a full-blown DW?

I experienced the same situation. The mechanic told me that one of my Dick Cepek tires in the front was out of round, so I threw it and put the spare tire on. After that, no more wobbling.

When that happens you can also put it on the back where it can't do as much mischief.
Of course, out-of-round is not good even on the back, so changing to the spare was probably the best way to handle it as long as the spare was still pretty close in size (if the other three are not too far worn down that is) and you can keep it there.
Not many things you can do to a Bronco that are quite as painful as having to buy four new tires when you least expect it!

We seem to waste the track bar bushings pretty regularly so a spare set on the shelf makes the jiggly wiggly go away pretty fast.
