Yeah, that's it Greg, up here in the salt belt they are prone to rotting out if not coated to protect them.

Personally, get a decent set of tires on Before you get an alignment done. The PS return line is an extended length piping, there are two sections to it, the shorter section is at the ps pump, it feeds down the front of the engine, there is a flexible hose on the end that connects to the major return piping that then feeds around the subframe to the front portion in front of the oilpan, then back along the same route all the way back to the rack. It's the total length of the return line that acts as a cooler for the fluid. Without any more info on your steering components condition I'll say this........when these cars were new there were issues with the steering wheel having a shimmy when *on center*, our car wasn't free of this issue, when at 8,000kms the steering developed that shimmy. It went back to the dealer who on the 1st visit replaced the ps pump thinking that the relief valve was fluttering, on the 2nd visit replaced the rack thinking the pressure seals inside were defective, on the 3rd visit removed all of the extended return piping to shorten up the distance between the rack & the ps pump in an effort to settle down any fluctuations in pressure. Doing #3 solved the issue with the shimmy. But that doesn't necessarily mean that doing #3 first could've/would've solved the issue.

^ Greg, what fluid are you making use of in the steering system? trans fluid or power steering fluid? Trans fluid is NOT the proper fluid for the system. It generally has a lower viscosity than power steering fluid, due to the friction modifiers can cause a whining in the pump, over time can ruin the seals in the rack, ps fluid is thicker & the system will function smoother. Seeing as the car is equipped with the 3.4 LQ1 is the original return line with the cooler extension in there? are you getting any sort of shimmy in the steering wheel when on center ( car is going straight)?
