I posted this somewhere else by accident. I think this is the right place

I have lifted my truck with 4" spindles. Should I do anything or is there anything I can do to make the front end stronger to compensate for the larger tires? It just doesn't seem like the front end is strong enough. Maybe I'm freaking out over nothing but. I here clunks and feel shakes and vibrations that were not there before. Every vehicle I own is lifted by me so I'm pretty familiar with how they drive. I also drive a Jeep TJ on 35s and a Z71 on 35s. My ranger has 4" spindles and a 3" BL, on brand new 31s. I know I know that 31s are to small but I got a killer deal on the BL so I got it LOL 33s are in the near future. Can anyone ease my mine or tell me what I should upgrade next?

Thanks this is my first post so please forgive any mistakes I may have made.

Without actually seeing, hearing and feeling what's going on with your truck it would be tough to tell. Larger tires and more aggressive tires always make some noise and vibrate a little.

When do you notice the clunks? Bumps? Acceleration? Stopping?

Need more information. But as always I'd start by looking for warn parts in the front end. Ball joints, sway bar links ect.

EDIT: What's your rear axle gearing? I'd bet a 3.55 or a 3.73 bigger tires need gears
