I have a 4" lift. And I'm running 37s with stock everything. Is this okay? I'm thinking of going back down to 35s. I started getting wobble so I took them off.

 

If you have a D30 up front, gussets, sleeves, and maybe a truss, depending on your wheeling style. How about drivelines as well??? I think those would be helpful

 

Did you check your wheel balance, and tow to start with? I take it from your post you are still using stock control arms? With 4" and 37's you will need adjustable control arms to set your axles back to center. Also if you have Auto front DS. Its also recommended to do steering flip kit to correct your steering geometry too. Also track bars. Im sure WOL, or someone else will be along shortly to give you more technical info. Good luck.

 

If you have a 4" lift, you don't have "stock everything". So which components came in the lift? Is anything adjustable? Did you check the torque on all suspension components? Did you check the steering components for wear? Were the tires balanced correctly? What are your caster and Toe specs?

If the 'wobble' started with the new tires, it may make sense that it is those new tires causing it. Get them rebalanced.

 

Actually, the axle tubes on the D44 are the same as a D30, so recommendations on gussets and sleeves should be the same for a D44.
