Frustrated vibes!! last chance for the 4runner
95 4runner Sr5 4x4 3.0 A340H(auto) 4.88 gears... and 179,000
and it has a vibration issue which I and 3 repair shops can't figure out where it's coming from.I would have thought that this issue would have been long gone by now but it's not...it has been 8 months sense I have purchased this 4runner and what a disappointment it has been so far or maybe I'm just frustrated..but it is still running and getting me to and from work 250 miles a week but for how much longer until it breaks down?..I carry about 150lbs of repair tools in the cargo area for such a thing because I don't know when it's going to just burn up

I have just about had it with this 4runner!.I'm not one to give up but I think I'm getting my butt kicked on this one, and if I can't fix it... then I'm going to sale it.I can't keep driving the 4runner knowing that something is going on with it and you know how that feels terrible terrible

I have spent over $2,000.00 in new parts(have all receipts) chasing this issue plus the price of the 4runner. I'm up to having almost $5,000.00 in a 4runner that is only worth well I don't know what it's worth but I'm sure it's not $5,000..I feel like I have given my all to this 4runner and even given up other things to put all my attention on trying to fix it but now I need to fix it or move on....

My issues again that I'm still having problems with starting with while engine is running and some things going on while moving
#1.)The engine running @ idle I can raise the rpms up to 2000 and start getting a vibration that I can feel while sitting in the seat.I can keep raising the rpms up to 3500-4000 and the vibration is really bad I can feel it through the auto shifter stick.I can feel the vibrations on the front bumper and front rims and steering wheel(while in park)
#2.)I can put the 4runner transmission in reverse engine idle 750rpms and it goes in gear easy with little bump.I go from Reverse to Drive and I get a somewhat long delay then a hard bump/hard slam, like there is a lot of play in the rotation transmission output shaft.The transmission feels like it shifts ok through all the gears but when driving and switching off the overdrive, I get a vary pronounced vibration I would call it and the shifter is really feeling like something is going on.I can accelerate and decelerate and feel a lot of slack in the drive train and when I put the transmission in Neutral I can still feel the vibration although it's not as bad
#3.)I feel that when the vibration is at it's worse while driving down the road rpms @ 4000 I can cut the engine, and it feels like the vibration goes away or is almost not noticeable at that point.I turn the ignition back on (4runner still rolling along)and the vibs are back
4.)While driving and coming to a stop I can feel a bump after I stop maybe it's the slack in the transmission or the torque converter?
#5.)I can feel a shaking in the 4runner while driving speeds above 40ish and seems to get worse the longer I drive it ,and can feel a bumping in the floor board,seat area and the auto shifter is bouncing around.I can here my tools in the cargo area clanging around.I also can here a humming some times and it sounds like a bearing of some kind trying to catch up with the rpms of the engine and it is rough feeling and does catch up with the rpms of the engine and will not be so bad at that point.It kinda smooths out at different rpms of the engine not sure if it's wheel bearing OR rear ring and pinion related
#6.)I can jack up the rear with tires above the ground start the engine and put it in Drive and I can feel a vibration while accelerating from speeds 20ish all the way up to about 60ish and can feel the vibration through the steering wheel and the 4runner is shaking OR bouncing badly and also when I decelerate .I can feel a hard bump when stopping the wheels.I turn off the engine and put the transmission in Neutral go to the rear tires and rotate them.I can feel some slack when one wheel is between turning the other(this may be normal?).I can also feel a clunking around and here some kind of noise while turning the wheels from both sides forwards and backwards maybe bad wheel bearings OR something clunking around in the transmission?

I have replaced the following parts trying to fix this issue
1.new tires & balance,new Cv shaft,new front inner & outer wheel bearings with cones and torqued per the FSM,new shocks all 4,front rotors & pads and caliper on drivers side,new center link,inner outer tie rod ends,pitman arm,idler arm,rear brake shoes and 1 drum, new u-joints on rear drive shaft (replaced twice for good measure) and they are in phase, rebuilt rear 3rd member(thought my original was bad but not the case)so I just replaced for nothing,TPS set per FMS,used VAFM working fine,Toyota plug wires.new plugs.dis cap & rotor,new valve cover gaskets,plenum gasket,drivers side motor mount,transmission mount,new air filter,fuel filter,changed all fluids in tranny,rear 3rd and front chunk,
I really don't know where to go from here.....I feel like the repair shop's didn't take the amount of time to diagnosis my problem or they really didn't know what was going on...not sure which is which
I will edit this when needed
any help will be appreciated
