100 series low speed crunching noise (1 Viewer)

[Mike Beauford]

Would appreciate some help diagnosing a crunching or grinding noise on my 2005 TLC. Have a mild 3 inch lift with a Slee front diff lift installed. Have had the dealer pack and install new oem bearings and new front brakes. Have also installed new oem cv axles, upper and lower control arms and inner and outer tie rods. Had a land cruiser speialty shop install new oem rack and pinion steering and oem power steering pump. Still getting the low speed crunching or grinding sound as I back out of my drive way or pull in. What else can I check?

“Still”, meaning it was grinding before you had all that stuff done?

What tire size are you running?

Also, are you running OEM upper control arms with a 3" lift? I think that'll cause some poor alignment issues. Not sure if that's related to your crunching, but could be a different problem.

Still. Yes I have been chasing this problem for a while. Running Toyo Open Country All Terrain AT II 275/70R18 E 10 ply which are 33.16 inches. The lower control arms are stock new oem toyota parts but upper control arms are regrettably aftermarket mevotech crap. Any recommendations for upper control arms the best deals with the 3 inch lift appreciated also.
