I just had the Calmini lift installed and have been getting a grinding noise. CV boots wereok but now the right one is has a torn boot. However, the shop that did the instal does not think it was the CV or U joint and wants to replace part of the drive shaft w/ a shaft from a Wrangler that happens to be the right size and will make the necessary height adjustment...they think. This is the first VX they have worked on and Calmini says they are unfamiliar w/ this occurence so they are kind of guessing as to this fix. I was hoping someone here would have info on this noise and may have a solution. Any help would be appreciated!
