I swapped my 93 hubs for a set of SN 95 hubs in spindles. I’ve done this before and I do not recall the alignment being this far off by swapping spindles. Anyone have any ideas or is this a matter of setting toe to compensate for the the different spindles?

Alignment is off or do you mean wheels are sticking out too far?

Are you sure they are 94-95 hubs?

The right tire is Turing inward like its turning left. The left side tire is almost straight. This is bizarre, I have never had this happen before.

Ohh. Well, that is odd. No idea other than maybe a bent mounting ear for one of the tie rod mounts or something.

Yeah, this makes no sense. You can see better from this angle.

Someone before me installed a Steeda Bump-Steer kit. Would that make a difference?

Having the toe drastically change is a common occurrence when swapping from fox spindles to SN95 spindles with no other changes.

center the steering rack, and eyeball the toe to as straight as you possibly can. You will want to veryify you have an adequate amount of threads engaged.

make sure all your suspension changes are complete and go align.

Be sure that you have the 1994/95 spindles, and not the 1996-04 spindles. The later spindles have the TRE mount offset a lot, which creates too much bump steer, and it cannot be fixed properly with a bump steer kit. If that's what you have, you can correct the toe in simply by adjusting it as Mike described. But the angle of the TRE's will not be parallel to the control arms. That's the test, the TRE and LCA should be parallel, a line from the inner joint to the outer joint of each, should be parallel.

I did just that. Centered the steering, eyeballed toe he best I could. It’s all straight now. It was weird, I have done 2 swaps on other foxbodys and never had this issue. There are other aftermarket parts previously installed. I need to get it to the alignment shop. It boggled me.

Thanks for the reply. I can’t wait to get it back on the road once this dang weather breaks!

I do have another question for you. I’m running 18/10 rear with 285/35 Conti DWS06+ front 235/40 same tire. I don’t like the front setup, I’m debating on 245/40 or 255/40. Which would you recommend or do you have another suggestion?

A 245/40/18 would be ~25.7" in OD, which is the stock tire diameter. 255/40/18 would be 26.0" so larger than stock. You risk of rubbing would be higher with this tire.

A 245/45-18 is 26.68 inches tall
The 245/40 is 25.7

sorry this is a lot.. and I hate long winded messages.
I was hoping someone was running a setup similar that could help point me in the right direction. I don’t want to flare or have rubbing issues.

I agree, I have been using a tire calc and I thing I have overthought this too much and looking for a second solid opinion. See pics

255 are 26” as you stated and have a 4” sidewall.
Compared to rear (1/10”) taller sidewall and (1/10”) overall larger OD.

245/40 has 25.7” with 3.9” sidewall (3/10”) smaller than rear.
Rear 285 have a 25.9” with 3.9” sidewall.
