1) Going by internet posts, Chevron Techron Concentrate is highly regarded. "They say" it is to be used before a stint of local driving as the PEA does it's cleaning upon shut-down.

1a.) I think I buy good quality fuel and believe my car benefits from regular longish trips (an 800 mile weekender once a month). I use the stuff annually.

2) The VR in my '02 fritzed and I ceased the opportunity to remove the alternator and had it rebuilt at a local shop. I believe anyone's 20 year old alternator would benefit from new bearings, freewheel pulley and whatever else they replace.

2a.) No problem removing mine and your's is the same so I can't offer any tips.

3) Consider replacing your control arm bushings with poly bushings. My local NAPA store charged $10 per bushing for the press work. It delivered a great, solid feel and those polys last forever they say.

3a.) PM sent regarding control arms.

4) No experience with A-1 Auto and the TQR parts they sell. The company surely does not have all parts for all cars.

I installed Sachs SuperTourings (said to make dampers for Volvo). Bilstein H4 and H6 models are said to be good. I installed H6's on a Saab and loved them and have H6's to go on my 2007.
