Rear Control Arms

[Mr Ramerton]

Hello,

If one rear control arm is bad from wear, should all 4 be replaced, or should they be replaced in pairs, or is it okay to just replace the bad one?

I know the right answer is to replace them all and that’s what i would do if i was doing the work. But the reason I asked is because the dealer replaced only one, the left lower under warranty and I was wondering if this is an acceptable industry standard?

Now the truck tracks to the left and right at random times under acceleration and I’m trying to figure out of it’s related to the rear control arms or if it’s from the inner and outer tie rod they replaced on the front left?

Thanks for any input.

Take it back and argue it, make them replace all 4 if at all possible
