Sorry for not searching before I post but how do you put this in words? Whenever I try and take off fast....ie kind of like a burnout (if you could) my gear shifter and 4x4 selector move to the passenger side and there is a little "grinding" noise. I'm pretty sure it is the trans mount.....? The main bolt that holds the trans to the bottom cross member has a gap on the very bottom. (if you look stright up through the hole in the cross member). I just want to confirm that this is the fix to my problem. thanks

Could be a motor mount too.

yeah it could the a motor mount or trans mount. if you cant visually see that the rubber is torn or separtated then get under there with a pry bar and pry up on the trans and see how much movement you get. sometimes you cant see the rubber has separted from the metal untill it is pried up, same thing on the motor mounts. that main HUGE nut on the transmount doesn't actually hold the mount to the crossmember that is just the solid connection for when the rubber does go out the mount isn't completely separated it will still have that big nut that keeps the tranny attached to the botton piece of the mount, its a safety thing.

iwould say motor mount, the "grinding" sound is the fan eating into the shroud

Yeah sounds more like a motor mount. However, if it's moving that much, the trans mount has probably broken by now also.

Hammerhead · « **Reply #5 on:** Feb 17, 2008, 07:57:58 PM »

Yep, that's a motor mount failure, from the sound of it. You may need to replace the drivers side mount and add a chain to limit the travel of the motor. I've had the DS mount get all buggered from really rompin' hard. The stock mounts are good for insulating the vibration of the engine but they are flexible enough to allow the engine to sort of tweak itself up on the drivers side so that the mount is lodged on itself and stops the motor from returning to the stock position.

Good stuff guys (or girls?) I thinks its the motor too because there is no way for the trans to move without the engin also. And the whole fan hitting the shroud sounds on the money. Too bad these mounts cost some money! For changing out the motor mounts.....how hard and do I have to suppor the engin...would a jack work? Are there aftermarket or just better quality mounts that I should consider? thanks again!

I used a floor jack and a peice of wood to jack up my engine, and I swapped to rock stomper engine mounts. theyre bulletproof. check out the new 4xinnovations trans mount too, its bad...

Nice. How much were they?(Stock ones look dubious to me to begin with)

Hammerhead · « **Reply #9 on:** Feb 21, 2008, 05:26:40 PM »

Those do look tough. Does the increased rigidity cause excessive vibration transfer to the chassis. I know that the body mounts can buffer vibration but if you have a rollcage tie-ins to the frame will you experience much increase in vibes and engine noise in the cab?

acerbis · « **Reply #10 on:** Feb 21, 2008, 09:14:10 PM »

i checked out 4x4 innovations and that trans mount and its for a gear driven transmission or transfer case......first of all is a 87 a gear driven one and second of all what other ones are out there and how else can they be driven?

Hammerhead · « **Reply #11 on:** Feb 22, 2008, 12:13:12 AM »

Yours is a gear drive

In '88 Toyota came out with the 3.0 V6 and it had a chain drive T-case

864runner · « **Reply #12 on:** Feb 23, 2008, 07:32:25 AM »

i have the rockstomper motor mounts and they do make the cab vibrate alot more than the stock motor mounts. it was really bad in the cab but once i hade the whole inside of the cab sprayed with bedliner stuff it made a huge difference in the noise.

here is a chart of the transfercases and transmissions with years and chain or gear driven, i cant rememeber what forum i found it on.

that reminds me, the rockstomper mounts will vibrate all the bolts out of the engine block if threadlocker is not used. the combo of the motor mounts and the 4xI trans mount does make alot of vibration noticeable to the driver, but torque at the wheels is improved alot.plus they wont break with low range wheeling.

I think around $75, which is a really good deal because stock costs alot more....

acerbis · « **Reply #14 on:** Feb 24, 2008, 07:26:44 PM »

Well it turned out to be the motor mounts. I pulled both of them off and there we in half! I did order the 4x4 inovations mount but have second thoughts about using it if all of the bolts holding my motor together fall out! I don't mind a little more vibes in the cab but if its going to create more work from lost bolts then thats not for me! It really will make my engin loose bolts?

864runner · « **Reply #15 on:** Feb 25, 2008, 10:44:03 AM »

it is a possibility of some of the bolts backing themselves out because of the vibrations that aren't dampened by the stock mounts. but it is also a possibiltiy that they will stay and you won't have any problems. it just depends how tight everything is already. when i built my motor is used blue locktight on a lot of the bolts because i knew i would have extra vibes from the rockstomper mounts, i havn't had any problems so far.

Hammerhead · « **Reply #16 on:** Feb 25, 2008, 02:54:02 PM »

If you don't use the Rockstomper mounts and opt for the stock mounts be sure to chain down the engine for offroad use. If you don't you will just trash more motor mounts.

TurtleTappers91 · « **Reply #17 on:** Feb 25, 2008, 04:26:18 PM »

Sorry I meant the bolts holding the motor mounts to the block will loosen. Not all the bolts in the whole motor...
Thats only like 8 bolts you need to lock tite. I have not had the 4XI trans mount in long enough to find problems. so far so good.....

acerbis · « **Reply #18 on:** Feb 25, 2008, 06:19:59 PM »

o....well if its just the motor mount bolts then I can handle that.

acerbis · « **Reply #19 on:** Mar 03, 2008, 04:19:23 PM »

i mounted the 4x4 inovations mount. Its a awsome looking piece of work. The vibes in the truck are a little more but I think i can deal with it. I'm thinking that it will looses up a little to. Everything feels nice and solid!
