Is my leaf spring bad?

    I'm trying to figure out what's causing a slight vibration during acceleration and deceleration, on a 2007 Tacoma Double cab 4WD TRD Sport (stock height) with 196K miles. Since I purchased it recently, I have replaced pads and rotors, Bilstein 4600 (front and rear) rear diff 80w90 with LSD additive, all 3 U joints (Spicer 5-213X) along with the carrier bearing. New Michelin Defender LTX M/S. I'm thinking it's the leaf springs since I have hard time gaining traction on dry road while accelerating from a stop. I can hear my tires spinning with slightly above average acceleration. On my test drive I was thinking "It's easy to spin the tires on this truck". This issue is felt from the seat / floor and goes away above 20MPH. It's not a bad vibration but I know it's there. The only way to prevent the vibration is (from a stop) if I release the brake and coast slightly, and slowly apply the gas. I know the leaf spring recall hasn't been done (It's on my list). Based on my search I have ruled out the U joints and carrier barrier since this issue was before and after I replaced those items. Thoughts?

    What did the diff fluid look like when you drained it? Any big metal shavings come out? (Fine particles are normal)
    Auto or manual trans?

    Auto trans, and the fluid was grey when it came out with no big chunks. I will say that after the change in the diff fluid, it did eliminate the vibration during acceleration in a turn.

    5100s and OME 885 coils front, 5100s and AAL for the TSB leaf pack (overload left in) rear. Jeraco camper shell.
    It's none other than AXLE WRAP! Common problem on these trucks due to weak rear leafs. Probably time for a swap.

    It's hard to say specifically on your truck.... But my 2015 (DCLB Sport 52k miles) had the same vibration as you are describing I recently installed OME Dakar (medium) leaf springs, B110 5100's and 6112's up front. My vibration is gone now, which is usually the opposite of what happens. I did notice that I was getting the taco lean even in the rear before installing new leaf springs which is odd.
