every lifted toyota truck will benefit from a cv rear driveshaft. with your standard driveshaft, the pinion should not be pointed up to the transfer case. if it is, it would definitely cause gear chatter and would be louder at different rpms and gears. I'm not saying it's the issue but it's a place to start. putting a cv shaft in my single cased 4runner made a big difference
Yes your right there are shims and the pinion is pointed up to the drive line, I'll talk to the guy at the shop, but the only reason I put the rear driveline in was to get an actual test drive in. I didn't trust the tranny I got. But anyways I plan on doing a 5" lift trail gear heavy duty leaf spring in the front with chevy 63" in the rear. I've already built my axles have everything hardware wize. Eliminating the old steering box/ arm system for crossover high steer and next gen box. Again anyways I would assume I should do the lift before I get the drive shaft made with the cv? And also what about the front drive shaft? Would it also need a cv?
