2012 LT suspension parts

[S1W99]

Pristine LT but is a little bumpy. 150K. I only drive around town so want to have a very smooth ride.

VIN: 1GNSCBE00CR255730

I'm interested in the order of replacement and best parts. I'm not sure OEM is worth the extra money but I'll hold off to hear advice.

I can't do a full rebuild all at once but need to get a smoother ride started.
I was thinking of shocks/struts and LCA bushing replacement first. Do I need to do the springs too?

I get a crunch sound from the front right and left depending when I back out and the tires drop off the curb as well as when I turn the wheel almost all the way to either side. Was hoping it's old shocks/struts.

I also have the Range OBDC plug to over ride the AFM.

Thanks!

I will start out with saying overall you Hoe looks pretty nice for age. I am looking to rebuild my suspension as well so i will be keeping tabs here. hope someone gets to you with helpful knowledge soon.

I got a mevotech front suspension kit from rock Auto. It included the upper control arms so I also ordered lower control arms and bill stain, front struts and rear shocks. Hope to have it installed in a few days.

On a similar boat -- just about reaching 200K on my 07 and I think its the stock, original suspension.

Swathdriver posted a nice thorough breakdown of all the parts to overhaul a suspension:

I just ordered last night the KYB Gas-a-adjust struts and shocks for all 4 corners, with new springs too from Rock Auto. Also changing out the inner and outer tie rods

 

[S1W99]

All parts installed. Not a huge difference, a little smoother. I don't think it was in that bad shape to begin with, but I wanted to get the creaking sounds out which the new ball joints took care of..

 

[S1W99]

Overall I'm glad I have new parts. I wish it was a little smoother at slow speeds in the. neighborhood but maybe that's the way it rides

I'm currently looking for part numbers for the most comfortable soft ride possible struts and/or shocks for my 2012 LT. The new struts and shocks I have practically throw me out of my seat going over potholes under 40 mph.

why not just go with OEM? i think thats what i'm planning to do. i've read that the monroe shocks will end up raising the front a tad.

What brand and size and air pressure with regards to the tires?

Remember this, GM offers customized shocks and struts depending on how your vehicle is equipped and optioned. Bilstein, Monroe, etc. offer very few part numbers and are not as customized to your suspension. Having said that, many prefer aftermarket struts and shocks.

Mine also has the dumb suspension and rides like an old Cadillac with OE parts and Michelin Defenders.

Michelin defenders. 275/55R20

There appears to be a lot of options. Trying to work through that now and find the struts and shocks that will give me the smoothest ride.

Didn't you post your RPO sheet on another thread or forum? Think I answered it a few days ago.

Anyhow, did you replace any other components of the strut assembly? The top mount and other components also play an important role in ride quality.

This is what was replaced as part of the mevotec kit. I also replaced the rear shocks with Bilstein 4600s

 

[S1W99]

I did however put this on recently... @iamdub

 

[swathdiver]

Well, the answer to my earlier question seems to be no. You really can't consider this a ZW7 suspension anymore because it is mostly a Mevotech suspension with Bilstein shocks and struts. You are still sporting the original bushings in the lower control arms, inner tie rods and all of the ten year old strut components and probably the same out back.

One thing I am not sure of, you are running 20 inch wheels, did it come with those originally? I thought all 20" wheel and tire cars came with the Z55 suspension on this generation?

 

[S1W99]

I

I also installed these lower control arms. Pardon for not including that. As for the tire and wheel size, it's what came with this vehicle.

 

[S1W99]

It came with this vehicle only means that that's what's on it when I bought it. No idea what it came with from the factory.

 

[S1W99]

Front struts are Acdelco 540-615 OE.

Do you think new springs will make any difference?

If you are at or near stock ride height, probably not much. But if you don't replace the other parts and check to see if there is play in the strut mounts the ride is not going to improve.
