Possible to switch the ss to ls or lt knuckles?
 

just looking for some info I tried searching and came up with nothing. is it possible to switch the ss knuckles bearings/hubs and cv axles to a ls or lt model? or should i take one of those knuckles to a machine shop and bore it out to fit an ss wheel bearing? had a bent knuckle from an accident and I'm having the hardest time finding one.

No. You need the correct knuckle. The ball joint mount is also different. Plus, I believe the geometry may be a little different between the 2.

The SS axles are probably too big to fit through the LS/LT knuckle.

Parts are getting scarce, check auto recycling yards I don’t see anything online at this time.
as for swapping in the LS/LT knuckles you would have to measure side by side, pretty sure they are completely different.

What side do you need? Here's a left

Won't be easy but it may be possible to repair the bent knuckle, depending on where and how badly it's bent.

the lt ls knuckle fits the ss hub doesn't, sadly I need the passenger side. the knuckle was done it looked like I had stanced one tire. had to replace a lot well ill mess around here and ill keep you all posted had some stamped arms so thought id try that route since the cv axles cost about 30 bucks each on rockauto for automatic. also have an lt knuckle so in theory id just need another knuckle to try this out.

fireman you are right the lt one is a bit smaller

The part RJ posted a link to is not for an SS , the EBay ad shows the RPO sticker, that was an LT with FE3 suspension
