I'm posting for my uncle who has an 06 Tacoma TRD Off road that he bought new. He's decided to keep the car even longer since it's been treating him well and asked me to change all the fluids. The car has 216k miles and has only had oil changed and the cabin filter after the fan failed. I believe spark plugs are original! since it's Denso on one side and NGK on the other. Engine Air filter was essentially clogged. Despite all of this, the car never misfired.
Anyways, after I changed the rear diff, the rear end has been vibrating bad, especially around 30-50mph. Here's what I did in order:
1)Valvoline 75w90 Synthetic
Vibration started, read about synthetic was a no no. He drove about 400 miles in that one week.
2)Valvoline 80w90 conventional
Vibration still there
3)CRC Limited Slip 7oz
No change
4) GM Limited Slip Oil 4oz
No Change
5) Coastal (Autozone House brand?) 85w140 conventional
Less vibration but still there
I did not see any LSD sticker on the rear diff nor the door jamb. There's a sticker for C9. It has an electronic diff lock.
Was I wrong to change the rear diff at 216k miles for the first time? It came out dark and thick with a goo on the magnetic drain plug.
What are the solutions to get rid of the vibrations?
