Rubbing after Fox 2.0 coilover’s install

Went to a different shop for an alignment today. According to the tech the LCA was maxed out and he was unable to move wheel forward or gain any more caster. Are they not doing the alignment correctly or am I screwed? Guessing I missed up putting the JBA UCA’s on with such a minimal lift at best, should of just kept the OEM on. So I can put the stock UCA back on or get a wheel with positive offset more like the stock wheel maybe like 25mm offset.

 

I don’t think you want 25mm offset. That would push the wheel even closer to the UCA. 0 offset is a safe spot with many liking -8 or -12 even moreso.

I also think you need a better alignment tech.

 

Paint your OEM UCAs red while they are off and then reinstall them. No point in having the JBAs with your setup.

 

Can you get a picture of the cams?

 

Several of the stock wheels, including my own, are +25. There shouldn't be an issue with those stock-like tires. OP did not say where he is rubbing, but I have been assuming it's on the wheel well or cab mount at full lock. OP, could you clarify?

 

I'm beginning to think the same.

 

It was rubbing on the wheel well and I did some trimming. But yes it rubs cab mounts at full lock or when turning with compression.

 

It baffles me why you are having trouble with 32's. I had less trouble fitting 33's. I'm starting to think you should put back the stock UCA, because it's the one wildcard.

One thing I did was take my truck to a shop that specializes in modified 4x4s to get it aligned. My regular shop was not familiar with SPC UCAs nor oversized tires. It took them 4+ hours just to mount and balance my tires. They were able to align my truck so that the tires didn't rub during casual driving, but they rubbed at full lock and partially stuffed. I've known them a long time and they've been good to me, but I will likely not have them do any speciality work in the future.

Care to share the new alignment sheet and some pics of your setup?

 

Your camber is still out of spec. Did they do anything at all? Take it to a different shop to get aligned and see if you can get your money back from the first one.

Your caster is out of spec as well, but many of us, including myself, run with more caster than spec and don't think it's an issue. Camber on the other hand can lead to uneven tire wear and handling issues.

 

They said that the camber was the best they could get.

 

You need a shop that is off-road specific to do your alignment, no way should you have rubbing issues with your setup.

 

That's nonsense. I'm guessing what they meant is that it's the best they do with the camber when the caster is maxed. If that is the case, I suggest you let them do a normal alignment with no constraints. I'm pretty sure people fit 32's without doing anything special. The talk about moving the wheel forward in the wheel well using an alignment usually involves 33" and larger tires.

If that is not the case, it sounds like something is messed up on the truck. Hopefully that is not the case.

 

Yes these tires and wheels were totally fine no rubbing before I added the coilovers and UCA.

 

I suggest you take the UCA off (it's not required) and/or take it to a different alignment shop.

Beyond that, maybe someone more knowledgable than me can look at the pics of your alignment tabs and make some suggestions.

 

That’s about where I’m at, I’m pretty sure the high caster UCA’s is the issue.

 

On other thought... you said 1" lift in your first post. Did you measure that or is that an assumption? If you were actually lifted say 3", it might explain the camber issue.

Also I just noticed you have Fox shocks. I'm not sure what diameter coil springs you have, but it's possible the stock UCAs might not clear them. It might be prudent to check with others before removing them.

 

Out of the box the Fox 2.0 coilovers add ~1” to 3rd gen and thats what I measured after they were installed. I have checked and those Fox 2.0 work fine with stock UCA.

 

Both camber and caster numbers are out of spec for this type of setup. JBA are not as good as SPC but that shouldn’t cause this issue. Go elsewhere
