Okay, so… Do I buy the 4x4 Timken?

I don’t see why not. These have been in thecopcar for 20k miles. Replaced original 4wd hubs at 190k.Okay, so… Do I buy the 4x4 Timken?
Does the PPV use a different LCA, or am I misremembering? I feel like there were both aluminum and steel lowers.
Timken seems like the right choice for hubs, but they do make two different part numbers at different price levels.
On uppers: Why not go beefier? The problem solver arms are thicker, and same with TTX.
The Moog CK "problem solver" arms aren't any more heavy duty, as far as the arm itself, at least not that I am aware of. The "Problem Solver" part is for the ball joints. Their advertising says...I think the 4WD and AWD models got the aluminum parts to help offset the additional weight from the front drive components. The XFE (eXtra Fuel Efficiency) models, although 2WD, got them as well for weight reduction. You can't mix-and-match between the setups because the ball joints are a different size and/or taper. You either switch everything (knuckle included) or nothing.
I haven't looked into this any further than recently seeing that they have an outsourced line from China or Korea or something like that. My guess is it's for them to offer premium quality vs. budget-priced options, just like AC Delco with their three tiers. Again- just my guess based on what I read recently and your mention of two different price levels. Back in the day, it was Timken, plain and simple: US-made, quality assured, etc.
If the OE arms regularly go 150K miles, what problem are they solving? As far as I know, it's the ball joints and bushings that are the wear items, not the arms bending or breaking. If I were to find undeniable accounts of the Problem Solver and TTX arms holding up as well as the OE arms for the same mileage, then I'd consider them. What I know of the beefier aftermarket brands is, while they may be made of heavier-duty parts, the wear points still seem to wear out much sooner. Go with what you know unless you need heavier-duty components that would over stress OE parts. Planning on doing some rigorous off-roading?

So Gusher bearing and greasable. The greasable part is why I went with them as I always felt like GM removing the zerk fittings on the factory parts was a stupid idea designed to save them money, not to extend the life or ease of maintenance for the end user.
- Problem Solver® Gusher Bearing -- Metal-to-metal design provides strength and allows grease to flow through bearing surface for reduced friction and long life
- Greasable Design -- Reduces corrosion and wear by allowing new lubricant to flush contaminants
- Keeps Dirt And Water Out -- Pre-installed dust boot shields socket components from wear-causing contaminants
- Absorbs Impact -- Belleville preload washer helps keep the bearing package tight as bearings wear
- Quiet Operation -- Premium pre-installed bushings with optimized stiffness inhibit noise for a more comfortable ride
GM cheaped out and found many ways to save money on the GMT900s compared to the GMT800s... no zerk fittings on front end components, no cabin air filter, no courtesy lights in the door panels, no lights under the hood just to name a few.
A. My PPV has aluminum LCAs. For handling?
B. The problem solver UCAs definitely appear to be thicker.
C. What are my options for upgraded bushings? Anything?
I noticed that the Nolathane site accepted my capital one cash back or whatever, so, I bought the sway bar package.
38mm front and 33mm rear.
Weeeeeeeeee!
