Hi I just purchased this 95 4runner 4x4 SR5 V6 and it has a vibration when it is driven.The vibration starts around 35/40 ish and seems to be worse 55/60 and when letting off the gas at a steddy speed 60 ish the vibration is there but not as bad, but when I slow down from that speed (not applying break) it vibrates reall bad.When I gas on it then the vibration smooths out some.

I have replaced the drive shaft u joints front/rear (someone said that was the prob) but no luck still vibrates.I guess not a loss cause @168,000
I have new pads/breaks turned rotors and drums, new shocks (not installed yet) gosh I just have been replacing stuff because the normal stuff was not done.I have changed the trans fluid & filter,oil ect

I had someone tell me it could be the transfer case yoke nut loose but I don't have a pounding vibration just a kinda rolling grinding or something like that

thanks for any info on this problem I don't want to give up on this because I'm allready attached to her ....
