On Ebay, they have these 8 pc, 12 pc, etc, kits that include upper and lower control arms with ball joints, sway bar links and tie rods....all for rediculous prices, even after shipping. Anyone bought one of these? What are your opinions ?
I looked at them too. The price is atrractive isn't it? But.....
When the lower ball joints break with out warning on a cold day - like we have in Cleveland and you have in Canada
The rear control will swing back. The tire will hit the the back of the fender. If your cars rusty it will ruin the lower front fender with the added bonus of slamming into the bottom of the cowl. Damaging that. Along with destroying the sway bar links. Then you get to have car flatbed towed to a shop to get fixed. Which will require a new control arm, sway bar link. And strut rod bushings. Like me you might figure it's a fluke - because the parts just aren't that old. And then two weeks later while your still recovering from the the first repair bill. BANG! You get to do the other side. And replace the rim in the process.
While I didn't use a kit fron Detroit Axle I did use budget lower control arms from Federated. A name I had trusted and literally sold thousands of parts back when I was a auto parts counterman. Never had any issues with that line. But in the decade or so I got out of the business suspension parts have changed from USA manufactured to mostly being sourced off shore.
MN12's have a extremely well designed front and rear suspension. But they are heavy cars and these parts are highly loaded. And it's only as strong as the weakest link. There are many places you can save money but any load bearing suspension parts are not one of them. This is the one area of the car you want to seek out the best parts and pay the price.
RockAuto does seem to have the best prices and inventory levels. And a little bird told me TCCoA members can get a 5% discount. While not a specific recommendation they do have a complete MOOG kit listed. Moogs moved a bunch of production offshore too.
Just my personal experience. I learned the hard way that this just isn't where you want to save a buck.
As far as the the budget suspension kit mentioned I'll echo the poster with the word death wish. Both of my LCA's broke at parking lot speeds. Had I been going highway speeds the outcome might have been entirely different. Buy budget springs, shocks alternators, oil filters, sway bar bushings maybe end links. If it's a load bearing suspension part buy the best. If not your sure ask yourself "What's going to happen if this breaks at 65 MPH or on a icy road"
