UCF20 - Rear Suspension Typical bushings etc???
So guys after reading all the stickies I notice we don't have a ton of information about rear suspension bushings or parts that need replacement commonly. What are the most common components in the rear arms etc that need replacing? Symptoms, tire wear signs etc? Ive also always had a slight feathering of the rears and just wondered what would cause it. My alignment has always been correct too.

2 most common rear issues are carrier arm bushings and strut rod bushings (aka the traction rod bushings).
carrier arm bushings can be had in poly to no major ill effect, but afaik it's not easy to source traction rod bushings. No big deal though, as you can get them reasonably cheap from lexus, and cheaper adjustable ones from Megan and Battle Version.
LCAs/Toe Rods are wear items but not a uniquely high wear items, same for UCAs.
Sway bar endlinks are almost always due for replacement at this age, though shouldn't cause tire wear issues.
What are your current toe/camber specs at ride height?

My toe is set to oem specs and camber is bery conservative at my current height being around -2.5 or less. I just threw the darn paper away. But I was driving lower for a while. Im going to get new rear tires mounted this friday and realign again. See how a conservative driving height does me for a few months.

PD nailed it.
The carrier bushings are pretty easy to spot, grab the arm and see if it moves... My bushing was completely separated and the arm was flopping back and forth. Made for a pretty serious clunk on hard accel and had an uneasiness when at speed on a winding road.
Sway bar bushings should be replaced about every 10-12 years or if you routinely drive over uneven roads where you are heavily loading one corner at a time.
Sway bar links in the rear don't see a lot of wear but should be replaced every 30k if you drive over rough roads or cobble stone and 50k if you drive on silken roads.

My '93 needs rear lower trailing arm bushings at the knuckle, my dealer only seems the whole knuckle for more than $600/ea, I found the bushings alone on www.partsgeek.com but they don't sell to Canada, so still looking. The car rides and drives fine but the rear end steps out when braking at higher speeds, otherwise you'd have no idea.

Thanks for the tip, found them already for cheap in a 2 pack, also found a good price on a power steering pump, gotta look into it first before I buy that though, not 100% sure I need it.
