i've been researching "noises after 3 inch lift" along with "vibrations after 3inch lift". But i'm coming somewhat emtpy handed on these searches because my shuddering/grinding is happening when i let my foot off the brake pedal without accelerating. That is, the shuddering/grinding happens as the truck is rolling at idle as opposed to the majority of people's grinding/noises/vibrations happening while they accelerate 25+mph. Moreover, when i accelerate the shuddering seems to go away.
To be clear, I have a 2008 sport prerunner DCLB and the lift is set to about 3 inches with camburg ucas. my alignment was done with acceptable measurements. my list of ideas from researching are the following:
- bad wheel bearing
- LS chatter (replace rear diff fluid)
- install CB drop kit
- take off my rear shims
- front brakes/ seized calipers
sorry for the long post. thanks in advance for your advices!
