300sd - letting the low end drag
 

After much debate and thought i have finally ordered new Lesjoforos coils for the rear of the SD. i also ordered 4 comfort bilsteins. i did not go with the HD because i want a comfortable ride and i drive alot on crappy roads.

i ordered 19mm spring spacers for the rear. the installation of these parts will coincide with new brakes, air filter mounts, front crankshaft seal, new starter and oil cooler lines.

my questions are
1. should i have them do the trail arm bushings as well? the differential bushing has already been replaced. i am replacing the rear springs because the low end sag and the scraping of the tire well coming up the driveway.

2. should i do the front springs? the front end seems fine.

i am also taking her to the upholster shop to fix the seats he will replace padding , fix the springs and add foam inside the springs for $300.

3. tranny fluid and filter change

while i am spending the money please provide insight on what should be done.

The car is in great shape the engine runs perfect , i keep up with the fluid, filters and valve adjustments. it will probably go to the detail shop to get the dings out of the doors and stains out of the carpet because of the lack of cup holders.

1. Trailing arm bushings are done on condition. Unfortunately, you usually cannot tell the condition until you remove the bushing. However if a jack is placed beneath the bushing and lifted, you can get an idea if the bushing is toast.

2. No

3. Every 30K miles..........without fail. Try to find the drain to the torque converter and drain it before adding new fluid, or the work is a bit of a waste of time............1/2 the fluid remains "old fluid".

we had it on the lift this morning and the trail arm bushings seemed fine, no cracks and still soft. i have not done the tranny service since i have had the car for 60k, so i hope i am still good.
