FYI, there are no "torque arms" in the front suspension. There is an upper triangle and front and rear triangle levers and they all have bushings. Your best bet is to refer to the front suspension diagram in the workshop manual for specifics. All bushings are specific to RR.
If it's front bushings on the differential torque arm then genuine only but the front suspension triangle bearing pins can be refurbished with a polyurethane bushing R A CHAPMAN in Australia and Introcar in the UK sell them.
The differential torque arm is in the rear. The front issue can also be shock bushings, triangle lever bushings both at the subframe as well as the large and small bushings that are pressed into the top triangle arm that has the offset caster bolt.
Car should be on a lift with an under hoist screw jack under the wheel to get the load off the suspension in order to diagnose where the issue is.
