Installing my Mevotech TTX lower control arms today, just installed their upper control arms like a month ago and the boot it already coming apart.

@Doubeleive When you say OEM what brand is that or does it just say oem?
ac delco. if you call any gm dealer parts department and give them the last 8 of your vin they can tell you the oem part number. generally you can find them cheaper on amazon. rockauto, ebay. just be sure it is actually ac delco not a bait and switch

Notes on the lower control arms. The zeros are facing forward without the ability to adjust that without repressing the ball joint but they do include zerk covers.

The lower ball joint boot seems to be turning with the knuckle in the picture you can see the boot it kind of twisted.

My kryptonite boots are still holding up… tried to tell ya!
Also Rudy’s diesel is the best place to get their parts if your in a rush I literally ordered another wheel bearing Thursday around 10 and by 11-12 it had been shipped and arrived at the house yesterday evening! Anywhere else would take a week or so to get it in!!!

Also just so you know kryptonite wheel bearings are pressed style bearings so you can run them without those cv axle tips in unlike the stock ones where if you don’t run the cv axle it could split apart
What’s nice about that is when you ever decide to put your cv axles back in there will be a hole there for them

I hear you guys. I’ve read conflicting info so I’m just figuring it out myself and updating you on the journey.

Next up is the steering rack and tie rods, any recommendations?

Apex chassis inners (hummer style) off custom offsets
And kryptonite outers IMO
I haven’t had good luck with my heim joint tie rod ends but it’s only because I’m running spacers to try and level them out if it weren’t for that I probably wouldn’t have a issue out of them they definitely took the slop out my steering it went from loose to like pinky finger tight I had to relearn how to drive it type way.
I ran the kryptonite ones for about a year before I sold my old truck and never had a issue out of them I know they used to have those green boots like mevotech and same issue they started cracking in no time but after they updated them with the new black boots I haven’t had a issue at all

is it leaking?
@Doubeleive It's leaking a little bit but the movement in the steering just ain't what it used to be and I'm getting a lot of clunking so I figured it's time to do the rack and that coupling joint that connects the steering shaft to the rack

New oem ones are kinda pricey, and from what I have heard the remaned ones can be hit n miss
whenever I have had a issue with one I have just grabbed a used one from the junkyard that had no visible leaks
the steering knuckle I see aftermarket ones for around $80 all day long a whole new oem one is like $450

the upper steering shaft has been known to "clunk" but that was on the gmt800's, supposedly they new design shouldn't clunk.
the previous fix was to shove some fresh grease in it and that would work for a while then it would start clunking again, then they came out with 2 more designs and dam things would still clunk

@Doubeleive The clunk seems to be related to body roll but there is no sway bar attached, the upper and lower control arms have been replaced, and the steering rack is bolted down tight.

I suspect the problem is the shaft within the rack is becoming loose and knocking around or body mount? I don’t live in a crusty area so rubber seems to live long where I’m at.

On a positive note the new balls joints helped a lot with the ride. Before I felt every bump on the road and got a lot of feedback in the steering wheel. Now the steering feels heavier but much more sturdy.

hard to say without hearing it/feeling it, mine will clunk going in & out of the driveway usually after it has rained or when the seasons change, all my gm's have done it. sometimes lubing the sway bar bushings resolves it but not always. I have mostly given up on trying to figure it out lol. all summer it's fine, dead quiet

I don't like to see that as I just did a complete front end rebuild of my 2014 PPV with all TTX parts. It is an on-road vehicle only so hopefully I will have better results. If not I guess I will test the lifetime warranty.

Working through Mevotech warranty claim currently will update. Might just be bad quality control because the other side is perfect

I just replaced my front tie rods with Mevotech and one of the packages was missing the bolts, cotter pin and zerk fitting. When I contacted Mevotech they told me to go out and buy the missing parts! Not the point!!

wow, even some of the low-life company's out there will at least mail you missing parts with proof of purchase.
