The rear lower control arm bushings on my 92 Civic are badly worn and need to be replaced. I've looked into what's involved in replacing them and it looks like a lot more work than I'd like to do, and like it needs a lot more specialty tools than I'd like to buy. I got an estimate from a shop to do the work and it's $600, which is also a lot more than I'd like to spend. Is there any reason not to just replace the whole arms with aftermarket ones, which come with new bushings? If this is the way to go, what should I look for to make sure I get good ones?
Absolutely - I've never done the work on a Civic, but you're probably going to have to take them off to swap the bush. I'm in the UK, but those LCA's are coming in at £100 ea, so at those prices, you could do the work yourself and get shiny new arms and bushes for half the price of what the shop is quoting.
Personally, as it's a 20 year old car, I'd just buy whatever arms your local autofactor sells.
