Hi..I'm also new so please bear with me. I have a 92 SC 400 that needs new control arms / bushings. I see a lot of postings in various places about supra control arms and replacement polyurethane product availability and some mention of stock replacement bushings, but haven't seen any postings of actual experiences. Has anyone out there actually done anything except replacing the stock control arms? Here's what I'd like to know: 1. If you use the polyurethane bushings as replacements...Do they Squeak? 2. What's up with the reference to Supra control arms? Do they actually fit or not? 3. And finally, if there are "factory" style replacement bushings out there..where can I get some? Sorry, if this posting is beating a dead horse,...but there's a lot of "maybe's" .."I think"..."I've heard that" etc.... and I'm not real proficient at searching the forums out there, but have spent a lot of time on vague info...thanks Steve
