I just found this awesome site last night and I hope to make alot of new friends here. I have a 89 Chevy K5 Blazer with a 350 tbi, 700R4 trans, NP 241 transfer case and 3.73 gears with a factory limited slip in the rearend. I have a 4" Tuff Country suspension lift and 33" BFG Mud Terrains with 10" aluminum baja wheels. What is the fix for the slight vibration I have because of the 4" lift? Is it the SYE kit or is there a CV style driveline available for the rear driveline? I don't do any rock crawling, I wheel in some mud, but most of my wheelin is in snow. Any help would be greatly appreciated! Thanks, Doug 4 wheelin's not a job, it's an adventure!
