ULTIMATE Guide to Quieting your Jeep Wrangler YJ: Comfortable Daily Driver

Today I install some sound deadening material in my 1994 Jeep Wrangler YJ Sahara. I took decibel readings for every condition, from a bare tub to double insulated at idle, 20MPH, 40MPH, and 50MPH. Thank you so much for watching, and I'd be happy to answer any questions!

Sùper detailed. I loved how you tooke a measurement at every step.

This is an extraordinarily well done video - thank you for taking the time to share your work with us!

[@NoGuaranteesGarage]

Thank you very much!

[@gregj7523]

keep in mind for the long term, thin steel sheets (your hood) disperse heat and that by dampening any areas designed to do just that, you increase the temperatures within those areas causing other controls to work harder to do their designated function - if you start noticing engine temperatures rise you may need to reverse the work you've applied - we understand your wanting to reduce noise levels, but you do need to balance that 'want' with the 'needs' of the vehicle operating properly (just a thought)

Very true! The cooling system in that Jeep is all brand new, and I think it would stay cool inside a volcano. If someone had some older or dirty parts of their cooling system, I think it could cause some issues

[@sushil1983]

Great information thank you, I will try it out on my YJ

[@NoGuaranteesGarage]

Good luck! Let me know how it goes, or if you have any questions!

Fantastic video ❤

Thank you!

Nicely done

Thank you!

[@toast_fairy1419]

Nice dude I'll definitely doing this when I get my yj, you have a sahara nice

[@NoGuaranteesGarage]

Thank you! It didn't always look that way. I've got pictures of everything, but no videos unfortunately. What year are you hoping to get?

You think an YJ Wrangler was loud try driving a CJ7. Bought it off the lot new in 1986. Those type vehicles are not boulevard cruisers. They’re utility. They’re meant to be loud.

[@NoGuaranteesGarage]

I mean, they're nearly identical vehicles outside of the front clip. Most people I spoke to before trying this gave me the same "it's a Jeep, it's meant to be loud", but most of those people don't daily drive theirs either

[@map3384]

@@NoGuaranteesGarage True. In 1986 if I gave the Jeep wave three times a week it was a lot. The Jeeps of old were made for the military, boarder control, post office, utility companies who needed to travel on unpaved roads. I didn’t care about the noise. They were fun to drive as long as you respected its limitations. CJs suspension was a whole lot different from a Wrangler. Very harsh. You won’t believe how easy it was to flip a CJ. Never did thank God. They really softened the Wrangler suspension to attract everyday drivers. When the YJ hit the dealer showroom in 1987 model year they sold like hot cakes.

@@map3384 My grandfather had a CJ7 before I was born. I never got to see it, but the pictures were enough to make me love them. I ended up with the red YJ because I couldn't afford one. Jeep definitely tried to make the YJs feel/appear safer than the CJs. I've even heard the square headlights were to encourage an appearance of stability

[@map3384]

@@NoGuaranteesGarage I was thinking of buying an old CJ. Should have never sold mine ages ago. I look around and can’t believe how expensive they are. Dennis Collins offers a great service for Jeep lovers in Texas but it comes with a hearty price. $40+ for an old CJ? Mine cost $11,890 new in 86. So I’m looking at a YJ.

[@NoGuaranteesGarage]

@@map3384 Do it! They've been increasing in value as they get harder and harder to find in good condition. Can always swap the front clips if you'd like

[@nonsequitur807]

Good info. What about Lizard Skin spray in sound/heat deadener

[@NoGuaranteesGarage]

From what I've read with Lizard Skin, it does a great job with the heat, but not so much with the sound. If this was a Jeep that got wet on the inside I'd probably use a coat of LS and then bedliner overtop

[@jerrykramer2537]

Did you do any temperature measurements or did you feel any reduction in temp when riding around?

[@NoGuaranteesGarage]

I didn't take any temp measurements, but I certainly felt a difference! That Jeep has AC, and it felt much stronger after all the insulation was down. Keep in mind, the engine also feels the difference too. If your cooling system isn't up to snuff, the new insulation will let you know quickly!

[@vortecmacs]

It’s a jeep. It’d be loved no matter what. JP not needed. Now the Delorean…
