Calmini lift w/ grinding noise problem

[drover65]

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!

Might help narrow it down if you can give more info. Does the grinding happen all the time, only when in motion, only during acceleration, only when turning...? Does the noise sound like it is coming fron the front, rear...? What does the grinding sound like? Have you checked to make sure the drive shafts are not rubbing the cross members or skid plates (if you have them)? Have you checked the brakes...the back plate may have gotten bent during the install? Did you change tire/wheel size at the same time? They could be rubbing the wheel wells.

They could be rubbing the wheel wells.

....thats where I'd look first.


BTW..the torn CV boot is normal...its been sitting at one angle for years...

...now its tweaked!

Same happened to me

most of the noise i have been getting hasn't started until i get up around 50 mph. it starts as a low pitched rubbing/grinding noise then builds in intensity. when i let off the pedal, it will stop but as i accelerate again and maybe gain another 5 - 10 mph, it will start again. it has gotten to where the floorboard will vibrate, which is how i first noticed it, with the sterreo up i did not hear it but turned it down after i felt the vibe. to me it sounded like it was coming from the front, but the tech at my shop said it is coming from the drive shaft because of the new angles.

Hi Drover....

Did you change rims and tires when you lifted ...if so...what sizes?
If you did change ...did you do any cladding trimming?

Just wondering if "at speed"....downforce is causing tires to rub...

On my way home from Moab I started getting some funny noises/ vibrations that I didn't get before Ldub lifted my VX in the parking lot of the Red Rock Inn. It was a super windy day during the drive and I got out and poked around to try and find the source of the noise. Mine ended up being the rear plastic inner fenders vibrating in the wind. The thing I'm talking about is actually the plastic, or fiberboard, "skirt" that is attached to the inner fender itself and hangs straight down. It was vibrating like crazy in the wind. Yours sounds a little more serious, but it might not hurt to take a look.

I have had the same problem, it happening because you drive shaft have different angle than stock now, and U joint working in different angle too!
