Are the nuts on the rear body mount bushings on a 2003 2500hd tack welded

So your main problem is body roll? Did you replace the swaybar bushings? Replacing my swaybar bushing on my 06 fixed my body roll problems. If you did, did you get the right size? There are 2 different sizes of bushings. $3500 for the front end??? Look at Detroit Axle next time. I did my entire suspension for $410, including hubs, shocks, struts, UCA, LCA, Links, inner, and outter tie rods.

Why do you want to remove it is damaged? If so a angle grinder is a good way to cut the weld . you will have to tack weld the new bolt to stop it turning while tightening the nut.

The best way would be to remove the battery and try to heat the nut and use a pair of grip pliers to remove the broken bolt.
Another way would be the remove the nut, this nut may be welded to tray. you will need to chisel it off and then use a regular nut. the only problem would be you should put a small tack weld on the nut to keep it from spinning next time you need to remove the battery.
The last thing is if it does not have a welded nut but rather a clip nut, in which you can pry if off by breaking the clip in two and removing it.

Cab mount bushings are a royal pain. From experience ypu may as well get new bolts and some nuts to fit while you are ordering the bushings. Also get new plates that mount against the bushings. It's not very common for any of these parts to be reusable. The front mount bolts may come out with a socket and strong arm but make sure you are using a 1/2" drive socket not the common 3/8. I believe the socket is 19mm. If the bolts break or won't unscrew you will have to cut a hole in the floor to get at the welded nut. There are 2 layers in the floor where the cab mounts are located. Measure from 2 access points to get an approximate location for the hole.

You can almost guarantee that you will have to cut holes in the floor to get the rear ones out. You will also have to remove the seat to get enough room to work on them.

Once you have to old ones out a small hydraulic jack and a block of wood will lift the cab enough to take the old mount out and install the new one. Use the block to support the cab when you jack so you don't dent the floor. Do them in pairs so the cab doesn't end up crooked on the frame. You can expect this to be an all day job. Hope this helps.

If this has a solid rear axle check the torsion(?) bar on the underside of the axle assembly. The welds have been known to break on them where it mounts to each side.

call dealer with VIN number to see if your car is involved. ALso, please explain which bushing. Safety Recall 98S36 - Certain 1986 - 1995 Taurus and Sable and 1988 - 1994 Continental Vehicles - Sub-Frame Rear Plate Nut Replacement AFFECTED VEHICLES Certain 1986-1995 Taurus and Sable and 1988-1994 Continental vehicles that were originally sold or are currently registered in the following U.S. states and Canadian Provinces: U.S. States: Connecticut Delaware District of Columbia Illinois Indiana Iowa Kansas Kentucky Maine Maryland Massachusetts Michigan Minnesota Missouri Nebraska New Hampshire New Jersey New York Ohio Pennsylvania Rhode Island Vermont Virginia West Virginia Wisconsin Canadian Provinces: Manitoba New Brunswick Newfoundland Nova Scotia Ontario Prince Edward Island Quebec REASONS FOR RECALL The body mounts on the rear corners of the sub-frame that support the engine and transmission may separate. This can occur if the lower retainer plate of the mount or the retaining plate nut becomes severely corroded from long term exposure to road salts and retention of moisture in the mounts. This corrosion can weaken the retainer plate of the mount or the retaining plate nut severely enough to allow the bolt head to pull through the washer or out of the nut. Should both rear mounts separate, the rear of the sub-frame will drop and steering may suddenly become difficult. This could result in an accident. SERVICE ACTION To correct this condition, dealers will replace the attaching bolts, plate nuts and the reinforcement plates on the bottom of the sub-frame rear body mounts, on all affected vehicles. SERVICE TRACKING

hello,it"s hard to tell,maybe visual check in your hood or trunk mounting if there is a loose welding or crank in body,or lift your car,visual check on rear suspension bushing,rear wheel bearing,propeller shaft bearing,ty

Just spot weld the nut to the body and cppe on working? Don't destory the nut but weld it. and keep moving. If you don'y want to do this you can replace the whole Front Axel adaptor, which you have to weld???

Good luck!

Section 04-02: Suspension and Wheel Hubs, Rear 1994 Town Car, Crown Victoria/Grand Marquis. Workshop Manual
REMOVAL AND INSTALLATION Spring Rear
Removal

1. Position a hoist under the rear axle housing, and raise the vehicle. Refer to Section 00-02 . Place jackstands under frame side rails.

1. Remove rear stabilizer bar as outlined.

1. Disconnect the lower studs of the two shock absorbers from the mounting brackets on the rear axle assembly .

1. Unsnap the RH parking brake rear cable and conduit (2A635) from RH upper arm retainer before lowering the rear axle assembly .

1. Lower the hoist and axle housing until the rear springs are released.

1. Remove rear spring and rear spring center mounting insulators (5741) from vehicle.
   -----------------------------------------------------------------

Shock Absorber Removal
Raise the vehicle on a hoist. 1. To assist in removing the upper attachment on shock absorbers using a plastic dust tube, place an open end wrench on the hex stamped into the dust tube's metal cap. For shock absorbers with a steel dust tube, simply grasp the tube to prevent stud rotation when loosening the retaining nut.

1. Remove the shock absorber retaining nut, washer, and insulator assembly from the stud on the upper side of the frame. Discard nut. Compress the shock absorber to clear the hole in the frame, and remove the inner insulator and washer from the upper retaining stud.
2. Remove the self-locking retaining nut, and disconnect the shock absorber lower stud from the mounting bracket on the rear axle tube.
3. Perform Shock Absorber Checks. Refer to Section 04-00 to determine shock absorbers performance.

Installation

1. Properly prime the new shock absorber . Refer to Section 04-00 , Shock Absorber Checks.

1. Place the inner washer and rear spring insulator (5536) on the upper retaining stud, and position the shock absorber so that the upper retaining stud enters the hole in the frame. While holding the shock absorber in this position, install a new rear spring insulator , washer and nut assembly on the upper side of the upper frame. Be sure to seat the rear spring insulator in the frame attaching hole. Tighten nut to 34-46 Nm (25-34 lb-ft).

1. Extend the shock absorber , and place the lower stud in the mounting bracket hole on the rear axle assembly housing. Install a new self-locking retaining nut. Tighten nut to 76.5-103.5 Nm (56-76 lb-ft).

1. Lower vehicle.

-----------------------------------------------------------------------------
Arm Lower
Removal
Refer to the illustration in Description and Operation. NOTE: To improve rear axle assembly noise and vibration concerns, the rear suspension should be fastened to the frame and rear axle assembly at the curb height position.
NOTE: If one rear suspension lower arm requires replacement, also replace the opposite rear suspension lower arm .
WARNING: TURN REAR SUSPENSION LEVELER COMPRESSOR SWITCH OFF (IF SO EQUIPPED).
NOTE: If both rear suspension arm and bushings and both rear suspension lower arms are to be removed at the same time, remove both rear springs as outlined under Rear Spring Removal. For air spring removal, refer to Section 04-05 .

1. Mark rear suspension shock absorber relative to protective sleeve with the vehicle in a static, level ground condition.

1. Remove rear stabilizer bar as outlined.

1. Raise the vehicle on a hoist, and place jackstands under the rear axle assembly . Refer to Section 00-02 .

1. Lower the hoist until the shock absorbers are fully extended to relieve rear spring pressure.

1. Support rear axle assembly under differential pinion nose as well as under rear axle assembly .

1. Remove and discard the lower arm pivot bolt and nut from the axle bracket. Then, disengage the rear suspension lower arm from the bracket.

1. Remove and discard the pivot bolt and nut from the frame bracket, and remove the rear suspension lower arm .
