Shop wasn't toasty but it was above freezing.
The rear upper control arms both had a bolt that had fused to the inside of the bushing.
That meant I had to replace the bolt, nut and add two washers each side after I ground off the old ones. Sweet. Spark shower emanating from your car while you work on it makes you look tough.
With nearly 400,000km on the odo and nearly 17 years of service I suppose I'll run into some serious rust and have to deal with it.
Now all funny noises from the suspension and steering system have ceased. Yay!
