Kbuskill's 2008 Burb LTZ "MOD" Thread

Only idiots experiment with their suspension.

[emoji1787] I got that one dub!

Are you leaving the coil spring and adding helper bags or just running the airbags? If you're leaving the coils, you should be fine. If not, it will have an exaggerated amount of body roll.

I haven't followed the whole process, I just recall seeing bags...

Just the TBSS bags, or air springs as GM calls them.

I already have 6" drop springs and Helper bags along with air shocks.

I am not sure how the compressor and relief valve works but maybe a simple system with two check valves in the pressure lines and a pair of relief valves independent of each other would work. I dunno how the pump is assembled.

Dump valve is built into the auto leveling compressor so if I put a check valve in line with each bag the rear would never dump once it lifted.

To put a relief/dump valve on each bag would make it manual dump and defeat the "auto" in auto leveling... lol

Who knows, you all may be (probably are) right and I may hate it and I may have to figure something else out, but I don't drive the truck like a race car so it may be fine for what I need.

Time will tell.

So the Moog rear upper control arms arrived yesterday.

They too are supposed to be RK series.

The box says RK series but the bag has this part number on it...

Kinda weird.

Kinda weird.

I thought the only difference between the RK and the CK was the warranty?

New Moog CK series upper and lower control arms, outer tie rod ends and SKF X-tracker Hybrid wheel hubs installed and the new polyurethane bushing upgrade kit installed on the steering rack.

Noticed a leak on one of the power steering lines so they will all get replaced.

New 305/40/22 Michelin tires and front end alignment done.

261,361 miles.

305 tires rub the wheel well liners slightly under certain conditions. Will have to massage the liners a little more.

My 14 yr old son is becoming quite the mechanic with my supervision since I am not able to do as much as I used to.

How did that bushing install go?

I'm not sure, everything I read said that the RK was their economy line and CK was their Premium line.

I know the CK series is their "Problem Solver" series for whatever that is worth. They market the problem solver stuff as being an improved design over stock.

You are correct though, the RK series has a 36 month warranty while the CK is lifetime.

Short Answer: R Series is a value-driven replacement part while the CK Series incorporates Moog’s premium Problem Solver components for a better than OE upgrade.

Are you talking about the poly bushing for the rack?

If so, it was a real pain to get the bushing back onto the rack once it was inside the bracket.

Yeah I was wrong- the K and CK is the same part while the RK has non replaceable ball joints. But I see a lot of chatter where plenty of people are confused since it seems at least some of them appear to be exactly the same part between CK and RK, like you’re experiencing- which leads me to believe that on something like rear control arms where there are no ball joints it’s possible they just sell them with different part numbers so they can charge more for the warranty but only have to produce one part which saves them money, or makes them money however you want to look at it.

Yes, thanks. I was concerned about that. I have some slop in mine I would like to eliminate. I was thinking about how to use the rack as a press to push it on if I do it. Or I was considering fabricating a more solid clamp arrangement.

I just started a chat with Moog Suspension.

This is an excerpt from that conversation...

*** Me...
I was just curious. You guys obviously used to carry a CK series for my truck but not now. Any idea why they stopped marketing these as CK?

Tammy J...
They are looking to make it easier to order parts and are starting to roll parts into 1 or 2 parts instead of 3-4 different numbers

Me...
So is the only difference between the RK and CK series the warranty?

Tammy J....
now it is yes, RK is 3 years and CK what is left of them is limited lifetime. I can send you the information if you will provide me with your email address... ***

So my guess is they are going to be phasing out the Lifetime warranty.

Still waiting on an email from them that is supposed to explain more.

Thanks for sharing this. I’m a little bummed. Seems like if they’re getting rid of the lifetime warranty, we may need to find another vendor to fill the [mostly good as OEM] space. [emoji20][emoji107]

I think Moog, which is part of Federal Mogul, was bought out by a huge megacorp a couple years back. Might be part of the issue.

Starting with the CK . "CK" designation, you are getting the same part. The CK are Moogs Premium line of control arms. Utilizing their "problem solver" technology, these control arms address common factory design issues providing a better than the original replacement for your vehicle. Most CK control arms include ball joints that are powder coated metal with gusher bearings giving them a long life. Many of these ball joints are serviceable and have grease fittings. The CK arms also have problem solver bushings and a precise fit and form for easy installation.

The RK series is a more value-driven part. Because there are so many different vehicles both foreign and domestic, Moog has introduced the R-Series arms to provide replacements for a wide range of vehicles. The RK arms have OE fit and form geometry alignment, with pre-installed OE style bushings and most include the ball joints. However, these ball joints are not serviceable like the CK arms. All of the R Series arms have Moog validated construction and design, providing a less expensive

Each line of control arms has Forged Steel, Stamped Steel, or Forged Aluminium arms to provide the best style for your specific vehicle. The Premium CK line has a limited lifetime warranty, and the RK has a 3 year warranty that are both handled through our awesome customer service team at DST. Whether you are looking for a "light on the wallet" OE replacement, or a "premium" control arm upgrade, Moog control arms are a great choice for your vehicle.

That’s EXACTLY what’s on their website word-for-word. Doesn’t sound like what she was saying before, does it? Plus they’re talking about front control arms only.

Yep... thats what I was thinking as well.

In the end, who knows. I will definitely be looking closely at the warranty offered on future purchases of Moog parts just to be safe.

Soon to be CUT Jeep coils! Or, maybe I'll skip my meds and just torch 'em instead.
