It's generally reccomended that you replace bushings\joints\shocks\springs\tires equally on both sides to maintain even handling.
IE: replace the front right LCA bushings, then do the left side as well.
If you can, if you do it in the front and there's a coresponding part in the rear, do it as well.
If you havn't done so already, take a look at your rear shock mounts, rear traling arm bushings, and lower control arm bushings, those are prone to fail abnormally soon in the non M- E36 line. Replace with M3 parts for better control, more responsive steering, and a phonominal handling boost.
There are some other common failures\problems with the E36. I've had RTAB's, LCAB's go bad, brake light fiassco's, and now my final stage unit is freaking out due to a bad resistor that's relitively easy to replace.
None of them are really expensive, they would be at the dealership but if you read FAQ's and how-to's, you can practically do every single one without a *whole bunch* of tools or a mechanic.
