Lower Control Arms

[Foggy]

SO I'm thinkin it's getting time for a front susp refresh. I've got 140K on the clock. I have
zero issues now, so it's just a preventative maintenance thing... Going to do struts, springs,
UCA's, Tie Rods, Etc
But what do you think about the LCA's...???? Should I just get new assemblies??? Or reuse
my OE and put in new ball joints and bushings?
And how hard is it going to be doing the bushings Or even necessary ???
Thanks

If you replace the ball joints only you still have old bushings unless you replace them too. All that work and tools and aggravation is more than a new OE control arm.

I did save my old ones, thinking I'd replace the wear items and have them ready in ten years but now they're getting closer and closer to the garbage. Same with my old calipers, springs, front diff mounts, etc.!

Ditto on the bushings or just a new LCA with everything.

Although I would say 140k is kinda low for a complete rebuild, no? My 99 Silverado got a front end rebuild at 260k. Everything was original except for shocks. I would jack up the front and do the "shake" test first before starting to replace things.

And also ditto on a lot of aftermarket parts not being as good as what comes originally with your truck, sometimes even the better brands that are supposed to be OEM.

I say OEM on the components. Aftermarket has become such chit over the past few years. If the LCA ball joint doesn't have any play, let it be. They last a long time, but depending on the roads and environment, 140k is about the time that play starts to show up. I ran mine with minimal play overlanding for thousands of miles - no change upon return with an additional 15k of road miles. They are durable.

However, I opted to replace the aluminum ones on my 2008 yukon when it had about 175k on them - a small amount of play in the ball joint but nothing serious. I spent the $800 to get OE ones from rock auto. I kept the OG ones in case I wanted to do as @swathdiver did, but who knows if they will be used again. My 2017 has almost 170k on the original ones with just a slight amount of play noticed on the last alignment - gonna run these to over 200k I'm sure.
