LCA bushing wear question.

My LCA bushings are worn completly out in the front on both sides but the back look normal.

Is the spacing suppose to be larger on the front vs back?

I have a new set of Whitline I'm going to install but I wanted to make sure there was not a larger problem first.

I replaced the rusted LCA with Moog that came with the bushings less than 40k miles ago. I'm not sure if this is normal or not.

 

It would hard to say what the spacing should be with a non-stock LCA. But bushings should not wear out in 40k. Especially ones which are as much of a pain to change out as the LCA bushings. But that's Moog parts for ya'.

 

Looks to me like the top pic is missing the washer on the left hand side between the tab on the frame and the bushing.

 

As @0xDEADBEEF said, you're missing a washer in that first pic. 40K miles is low, but could be reasonable depending on the type of driving you do, your climate, and most importantly what your alignment cams look like in order to acheive a good alignment. The Whitelines may not give you much more than that (they'll certainly not last as long as OEM rubber) but they will give you better handling and usually a nicer alignment. They may be squeakier as well, since they are poly instead of rubber. You can mitigate that somewhat by adding a grease zerk (and then using it to grease them over time!)

I just went through replacing all my bushings and adding zerks; wrote up (with photos) how to go about it, in case it's helpful for you or anyone else:

@turbodb
Did you wave white lines before you put thoes polly bushings in? I know my whitelines allow for a far amount of play in front to back movement.

 

My whitelines went in tight, although some of that might be the thiccness of the spc cam washers

 

By wave, do you mean run? I've never run whitelines, but I've helped to install them on other people's trucks a couple times. I think they are good bushings in general, but they have the same drawback to OEM (IMO) which is that they are sleeved, and so future removal is always a bit iffy/tedious depending on the rust-in factor. My hope is that with the Strongflex, which are 100% poly and a tight fit into the LCA, future service is much easier (albeit, they are more costly).

Additionally - and I don't know how much this matters yet - the Strongflex are going to be easier to grease, b/c all I need to do is squeeze grease into the LCA race, and I don't need an aligned hole drilled through the Whilteline sleeve as well. Time will tell.

 

Not knowing how long it's been since you put in the Whiteline bushings, do you remember if the ride quality changed significantly afterward? I just did that job a few weeks ago, and it seems I can feel every crack in the road more than before, and I wouldn't have thought the poly bushings would have made that much difference. It could also be due to something else, and not entirely the poly bushings. They did eliminate the squawking LCA oem bushing noise, though...

 

eh mine has never ridden great, so it’s hard to tell.

but I think I’ve seen people say that about poly bushings in general, they’re not as soft as the oem ones.

 

It's fine at higher speeds, it's just around 10-25 mph, I can feel every road imperfection. I don't remember that impression from before. I thought the tires might be overinflated, but they are at 32psi, so...the tires are pretty worn, though. A new set is in the offing.

Thanks for the response.
