2021 MagRide blown strut

So my 2021 Yukon Denali with 75k on it has blown a front right strut.

I’ve just purchased 2 new OEM struts for a whopping $959. I’m trying to get to the bottom of what I’ve been told.
1. I was told I need to replace both struts at the same time(not a bad idea) but not when they’re $400 something a strut.
2. They need to be programmed after install or they will not sync…..


The struts I bought from the dealer didn’t come with a complete connector just 2 wire prongs to connect to the existing connector. Normal?

I was quoted around 4K for parts and install, I’m choosing to install myself.

Looking for tips on anyone who’s installed at home with no issues.
Main questions are the “programming” do I really need to???

&any extra parts you found you needed to complete the job.

Thanks!

First, I'm not aware of any "required" programming after a replacement installation. It probably makes sense to perform the Automatic Level Control (ALC) procedure, using a quality bi-directional scanner to ensure a completely level truck with the replaced shocks, but it is not required.

Second, unless you have a professional garage quality HEAVY duty spring compressor, you should not attempt to disassemble/reassemble the struts yourself, as without the correct tool, it is extremely dangerous to your health. When I replaced my front shocks, I removed them from the truck myself (easy), took them and the new shocks to a local repair shop with a heavy duty spring compressor and had them perform the disassemble/replace/reassemble the strut assembly. Then I took them home and installed them. The rear shocks can be easily replaced by yourself.

The plug for the wire connector is attached to the wiring feed, and it simply plugs into the shock after installation.

For the best pricing, go to RockAuto.com and/or GMPartsDirect.com, and you should be around $350 per shock. Also, the new replacement OEM Magneride shocks come with a lifetime warranty.

This is all you need to know as @Joseph Garcia just stated. I concur 100%. I've done these style up front and they are cake to install. Having the proper spring compressor is key. I never had to reprogram any struts I put in. IF there aren't active codes present, I'd put on a pair and be done with it.

The 2 wire thing is a pain in the butt, but it's a Deutch connector, so you release the pins/body with special tools and then reinstall the connector onto the new wires. Just mark where each goes before disassembly.

I thought the rear shock is a strut design similar to the front on these IRS models? Are the coil springs and rear shocks divorced?


Would a spring compressor like this suffice? I'm not a fan of the inexpensive types like this:

It may well be a strut-type setup in the rear in your model year, as I am not truly familiar with your model year. Hopefully, a member with a model year the same as your will chime in with an answer. If your model year does in fact have struts all around, my original reply does not change that much, as you would instead, bring all 4 struts to a local repair shop.

Your displayed spring compressors are NOT nearly heavy enough to safely perform this operation on your truck's struts. I used the spring compressors in your second attachment on my little Honda Fit, and it was not a comfortable procedure for me. Do not play with fire here, or you could get severely injured.

For what it's worth, I just had all 4 of mine done for about $2,800.00. In my experience, you can get far better pricing at independent shops than at dealerships.

I have done all 4 myself to install the lift kit. This style spring compressor works fine.


Its a bit of work to get the front off.
