need some help, have to change the motor mounts on my 99 T/A is this a big job or is this something i can do myself

it's simple on paper, took me a few hours I could do it again in one or two

1) jack the front of the car up enough where it's comfortable for you to work on it, remember to use jack stands, dont want to be squished on your driveway

2)start to jack up the motor, by putting a block of wood between the jack and oil pan,

3)both mounts have a large long bolt going through them, remove these bolts once the pressure of the motor is off and jack the motor all the way out of the mounts.

4)replace the mounts. do NOT put the mounts on the motor, then lower the motor back in place, it WONT work; the mounts must be tightened to the body before the motor is dropped back on.

5) use a bar to wedge the motor back into the mounts and replace the long bolt on each side.

6) you are done

NOTE: if you have a 6 speed, replace the tranny mount too, it is much, much easier to replace than the motor mounts and will prevent wear on them too.

Without a doubt, best advice you can take! Take the pedestals out with the mounts but only do ONE SIDE AT A TIME. I made the mistake of taking both off and got one on in no time but fought for hours to get the second side to line up because the motor shifted.

Agreed. And while you have the pass side out reverse the long bolt that goes between the pedestal and mount shell so that you can just pull the mount if there is a next time.

i reversed the bolts........it was great...........til i put the headers in........headers blocked the bolts......turned the bolts back around

I have to change mine and i bought the clamshell inserts and its says you have to drill out 5 rivits holding the halves together is that hard to do? im guessing you have to unbolt it from the frame and take it out

[jiveass]

you can remove the pedastals or remove the alternator and ac pump to get the bolts out.....i actually removed it all cause i installed poly mounts and its hard to line up the holes with poly mounts....pedastals had to be removed.

so ill have to unbolt it from the motor and the frame and take the whole thing out do you have to do that on the driver side as well?

[jiveass]

if youre goin back with stock mounts, you dont HAVE to take the pedastals out. but you do have to remove the alternator and ac pump to get the long bolts out...

No i have th polyurathane inserts

No i have th polyurathane inserts

heres the lowdown, slick....i had to pull the pedastals as well, (at least get em loose enough to move around a bit) because the poly mount is such a tight fit in the clamshell, there is no forgiveness for the inaccuracy...i fought with it for a few hours before i decided to unbolt the pedastals, after that , gravy train with biscuit wheels.

i got stuck with some short ass jackstands to work with so it sucked...and be careful where you place the jackstands...if placed in the wrong spot, it could hinder your access to the mounts....i learned this the hard way....
