Lift & tires help

I had a set of 5100's set at 1.75 and 265/70/17 trail grapplers. After I had all this installed I have noticed it feels like my front end kinda wonders a little going down the road. Is this an alignment issue ??

 

Did you get alignment done after installing your lift? Because it is pretty much mandatory that you do.

 

Are your tie rods tight?

 

Ditto. ^^ Also, the tires could have some pull that you'll just have to get used to. Even after alignment, my Toyos still have some pull/wander that just is what it is. Plus don't forget to re-aim your headlights now that you've raised the front end.

 

Yes I had an alinement done after the lift and it was there after the lift. Then I went back and had the 1/4 '' spacer added so they did another alinement and it was a lot better. Now I have put on the new tires and it is worse. I didn't know if a good alinement person might get it right. My local yoda dealership ain't hitting on a lot

 

How much lift did you end up getting? If it's close to 2.5" or more, you probably need new UCAs.

 

If you're only at 1.75, and have the lean spacer on the driver side, I don't think you will need after market UCA's. It sounds like there is some sort of alignment issue though. It could be slightly out, maybe due to the shops alignment machine being out of calibration, the Tech may have not set the Caster to different specs, or you may have a Toe issue. What it really sounds like is the Caster. Common practice when setting the caster, is to have one side a little more than the other due to the variation of pitch in the road. Don't quote me on this, but I think it is the drivers side that should be over some, say 2.5* passenger and 3.0* driver. Alot of times, the tech will put the alignment to "factory spec" which on their machine reads 0.0*, when in actuality it is 2.5*. So if it is "factory spec" then one side needs to be 0.0* and the other 0.5*. An older, more knowledgeable tech would know this, and just do it out of habbit, where as a noob wouldn't. Check your last alignment sheet for what the numbers are reading, and see if you can post a pic here. Also, if you have the availability to do so, check that all of the suspension fasteners are torqued correctly, a loose suspension component could cause your problem as well. Good luck.
