I know many of you are sick of hearing this, but im still trying. What I was wondering what everyones thoughts are here, cause im literally sick of my T100 but I cannot afford anything else really right now.
1996 T100 3.4L V6, auto, 4wd, x-cab.
Heres what happens:
If you take off you can feel a profound movement on the drivers side rear of the truck. Kinda like wheel hop I guess is best to describe. Once i get to about 20mph you can feel the vibration when on the gas.
At speed I can feel a vibe right under my feet, actually right where the cab mounts are but it also vibes the entire truck as I go too. On the gas only do I feel it, while coasting along its barely there if at all. Step on gas again and it comes back.
Here is what I have diagnosed/done:
-Replaced passenger side rear axle shaft-the vibration lessened to a degree.
-Replaced trans mount (rubber was worn and coming off but no effect)
-Checked motor mounts. Drivers side seems to be looser of the two. Both seem to have play in them more than I expect. I dont know how much is bad tho, but I can wiggle the drivers side a good 1/2 inch or more. I bought new ones but havent gotten around to installing them.
-Checked the cab mount bushings, all are worn out BAD and i bought new but dont have time to replace right now. Right under the drivers door I can push the mount back and forth a good 1/2 inch or better.
-Noticed this bushing that connects part of the front differential to the whole front suspension is FLAKING apart. Gonna replace that I guess if I can get it from toyota.
-Replaced all shocks with HD
-Checked vehicle with rear drive shaft disconnected and off, the vibe still existed in what equates to fwd, in all gears..maybe not as bad however. The rear still spins if the tires go. But in the air it seemed tohappen too with only the fronts going.
-Had both driveshafts checked and balanced, had the propeller shaft replaced. Didnt seem to help but eliminated them from being an issue.
-Front CVs seem fine, dont seem to be bent, nothings leaking out of them.
-Replaced all brakes, calipers, rotors, shoes, drums, and rear wheel cylinders.
-New tires and wheels balanced perfectly and re checked again to be sure.
-Front end seems to be loose despite new idler arm, pitman arm, and all balljoints, tie rods and centerlink are fine and have no play. New steering stabilizer too. I have a small side to side play and can hear a decent clack when i push the wheels forward and back.
-Motor seems tight as does trans, engine runs very well and trans shifts super smooth and good. Also the motor was totally redone about 60k ago by previous owner with receipts from toyota.
-You can watch the 4wd shifter wiggle back and forth as you take off. It wiggles quite a bit but I dont have anything to compare it too.
-Added these small helper springs that sit on top of the leaf pack and take up slack-seems to have lessened the vibration and wheel hop a bit. This seems to have had the best effect. I would assume after 200k my springs are worn out but enough to cause axle wrap this bad I doubt it. It was 400-600 bucks for them to rearch and rework my springs after i called 5 different places and i didnt do it cause of the cost.
-I cannot tell if the flexplate is bad in the trans but the engine and trans connection has no play it seems.
So thats where I am at, i am gonna install the mounts when i get a chance and take it from there. I am thinking the drivers side shaft (although it had the same amount of play the pass replaced side does)is no good and bent. It makes sense b/c of the wheel hop and vibe at speed in any gear and in fwd too b/c although its disconnected the shaft still turns as you move no?
I just dunno anymore, I wanted to buy a newer tundra but at 10K plus they are being sold for I cant afford it. I really love this truck but its getting to me.
