When I bought my Mark VIII back in November, the previous owner had both driver's side control arms replaced.

It was done by a mechanic, but I have no idea what the brand of these arms is.

They certainly are Mark VIII arms, since the upper has the ball stud for the ride height sensor.

Anyways the lower control arm says 'Made in Taiwan' (yikes) and is not greaseable and has a black dust boot with a greenish retaining ring around the boot. It is not a castle nut, but a nylon locknut on the ball joint. Going by the pictures on RockAuto it kinda looks like it might be a Moog R-Series, but I thought they were still made in the USA/Canada.

Neither the upper or lower have play in them, but I'm kinda worried about what brand it is. I highly doubt they're eBay as the last owner took it to a shop, but I'd rather be safe than sorry.

Also, the LCA casting looks good, not like the eBay ones that look like they were molded by a three year old lol.

Thanks for the help!

Got any pictures? Those would help immensely...

FWIW, Moog's "R" series are their low end 'economy' products. On par with the cheap ebay crap IMHO...

I can get some pics, but how do I post them before hitting 50 posts?

Also forgot to mention that the passenger side lca that I recently replaced to fix my brake pull was in fact an r-series. No wonder it was so cheap locally.

Strange thing is... the box and the ball joint both said Moog 'the Problem Solver' I thought the r-series wasn't problem solver?

Use Photobucket, I don't know where you got the notion you need 50 posts, there's no postcount limit on anything but marketplace.
My posting rules say 'may not post attachments' so I always figured I had to hit 50 posts before uploading images.

Anyways, it's -29 here right now so I'll crawl under the car and take a pic hopefully tomorrow when it warms up to a balmy -3 :thumbsd:

Better late than never! Finally got some pics (really bad pics btw). I noticed that the upper control arm had TRW stamped in it and had a green snap ring around the boot yay!

The last owner did the uca and lca on the driver's side at the same time, so hopefully the lca is a TRW or equivalent.

Note that the LCA has very little rust on it, even though it's a year older than my moog lca, which is ONE MONTH old and is covered in rust :facepalm:

If anyone recognizes the lca in the pics please let me know!

LCA to spindle



TRW UCA



Not very informative I know.

Sorry for the crappy pics

Judging from the boots and lack of a grease fitting I'd say raybestos SERVICE grade or mevotech.

I wouldn't replace them until the boots get torn or they exhibit clunks and or noises. Don't fork out the cash to replace them just because you don't know what brand they are. Chances are if a shop did it they aren't that poor of quality (See: Ebay special). About the only reliable uppers left are Ray Pro grades, Moogs PS's are pretty much economy level now...Sadly.


A long as they aren't ebay arms.....If it ain't broke don't fix it. :D

Yeah they do look like the mevotech cheapies.

I'll leave it in there for now. Mevotech original grades have a five year warranty, so they can't be that bad.
