I need to remove and replace the engine cradle/subframe on my 98 lesabre. I see one bushing listed but references to body position 1 or body position 2 and I do not understand those positions.

Secure the drive axle to the steering knuckle/strut.
Adjust the jackstand to lower the left side of the frame until it hangs free. Remove jack stand.
Lower vehicle to access engine support fixture.
Lower the engine/transmission assembly with the engine support fixture to gain access to remaining side cover bolts.
If replacing the side cover, remove 4 engine mount bracket bolts.
Remove the harness retainer.
Raise vehicle to access side cover bolts.
Remove the case side cover bolts (56-58).
Remove the case side cover pan (53).
Remove the case side cover gasket (54).
Clean the case.
Clean the side cover gasket mating surfaces.

Disconnect the wiring harness assembly from the fluid temperature sensor (391).
Remove the fluid temperature sensor (391).
Installation Procedure
Install the fluid temperature sensor (391).
Connect the wiring harness assembly to the with fluid temperature sensor (391).
Install the case side cover. Refer to Control Valve Body Cover Replacement .
Important: It is recommended that transmission adaptive pressure (TAP) information be reset. Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, The ECM, PCM or TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.
Reset the TAP values. Refer to Transmission Adaptive Functions .

if it is a unibody then it will have an engine cradle or sub-frame that supports the engine and transmission. If you plan on replacing the subframe you will need to support the engine and transmission from the top side with an engine support fixture.






Subframe/cradle





I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

Hi Evelyn.here's a link on your oil pan removal,it says engine removal,will send a link on that too. SAVE 20 ON ONLINE SHIP TO HOME ORDERS OF 100 OR MORE Here's the engine removal guide. SAVE 20 ON ONLINE SHIP TO HOME ORDERS OF 100 OR MORE

This would be very rare and have never heard of it happening.

The Subframe is a metal frame like enclosure that surrounds the Engine /Transmission. The Engine/ Trans drops into the Subframe and in turn is bolted to it via Engine Mounts and the Subframe is in turn bolted to the uni-body of your car via Subframe Mounts.

yes and in order to remove subframe you need a engine cradle bar to that attaches to the engine under the hood and rests on shock towers and front of radiator holds the engine in place for subframe and trans removal. this is a very laboress job. good luck

you will ned to have the front of the car well off the ground wheel and all to do this repair. once car is up it will need to be supported at the pinch welds behind the front wheels on the body and body only. because you will need to drop the subframe/craddle a few inches.

now once that is done you will need to work with 1/2" tool's for the added torque and leverage. the two rear bolts holding subframe up are where the mount bushing you speak of are located. the bolts are21mm or 22mm insize meaning you need that size socket to remove them. remove both rear ones but you will need a jack under the middle of the rear of the sun=bframe to lower and rise it too swap the mounts. once both bolts are out lower the jack to lower the subframe and you will be able to replace mounts and the install is reverse.

if you have any more question please ask and good luck. be very carefule

LOWER CONTROL ARM

REMOVAL
1) Raise and support vehicle. 3) Remove the steering knuckle.
Remove the bolts fastening the power steering cooler to the front suspension cradle crossmember reinforcement (Fig. 21). 5) Remove the lower control arm rear bushing retainer bolts located on each side of each lower control arm rear bushing. NOTE: The bolts fastening the cradle crossmember reinforcement are of three different thread sizes. Note the location of the various sizes.

6) Remove the bolts attaching the cradle crossmember reinforcement to the front suspension cradle crossmember (Fig. 22). Remove the 2 bolts fastening the reinforcement and rear of cradle crossmember to the body of the vehicle. Remove the reinforcement. 7) Remove the pivot bolt attaching the front bushing of the lower control arm to the front suspension cradle crossmember. 8) Remove the lower control arm.

It is highly unlikely that the bushings will fail. They do tend to crack alittle, but the bolts will still hold the subframe on. Now if they are rusted out, this is a possibility. You do have 4 bushings holding the subframe on also. 2 at the front, and 2 at the back.

please rate highly if this helps
