New axle - steering wobble

I have a wobble in the steering wheel with the new HPd30 I installed. Around 35-40 the steering wheel wobbles unnervingly, but it isn't death wobble. My previous LPd30 didn't have this, it is new. I also didn't notice it when I had 600-800 lbs of gear in the Jeep last week.

Rebuilt axle. New ball joints. New CA bushings at the axle. New track bar. Shop aligned it after I installed. Shop rebalanced the tires.

Here's my guess, but what else should I consider? Since I didn't notice it with the weight in the Jeep my guess is it could be related to caster angle. More weight increased the caster. That's all I got, what you got?

Most likely is driveshaft angle, maybe the shop pointed pinion down too far to get caster higher and u joint is creating the vibration. Or just that its a high pinion axle the u joint is not at the angle it previously was. Did you install a new u joint and check the angle on it?

Did they crank up the air pressure in the tires after the balance? Check easy things first

Driveshaft vibes and steering wobble are two different things.

Go back to the shop who did all the work.

Get them to check the balance of all tires and the alignment specs (Toe in, caster etc) Try a simple tire swap, front to back and try to duplicate it. Might be a process of elimination.

Ok, too many to quote here so I'll just respond in bulk. Thanks for the help.
  • Tire pressure has been checked and adjusted. I should have mentioned that in the first post.
  • There isn't a track bar drop. Not sure why that came up, Loukaps
  • I did all the work, not a shop.
  • This isn't vibes. It is a speed related steering wobble.

I am pretty sure you have a tire balance issue. Otherwise you would feel this wobble at more than one speed

Caster angle would be my guess too. Did shop only adjust toe?

Go check your balance again on the tires or rotate them and see if problem persists.

The shop I was referring to is the alignment shop. They may have some input into the problem.
