Eliminating Cabin Noise?

[motoxchamp]

I love my ranger 4.0 but I would like a quieter cabin. Is there anything I can do to reduce cabin noise? I especially don't like the wind noise created when I am on the highway. Dynamat will not work in this case but will thicker rubber around the door make a difference? Is there a way to get a better seal on the windows?

You're not going to like the answer, but it's to sell the truck and buy a small luxury car.

Wind noise comes from turbulent regions, which will only be removed by changing the shape of the vehicle. In particular, EVERY pickup truck has a big nasty vortex right behind the cab. It's the flat trailing edge that does that, and it's really hard to make a pickup that doesn't have that.

You also get noise from everything that sticks out from the sides. Like mirrors, trim, window channels, and so on.

As for ENGINE noise, ditch the "performance" parts. Quiet operation is not a performance concern.

For tire noise, a good road tire will quiet it down a lot, but they get kinda expensive. Michelin LTXs aren't bad.

You can try wrapping the inside of the truck with "sound deadener," but it will only go so far.

Ventshades for the windows will quiet down windnoise unless you have a really stiff crosswind then they seem to make some of their own. You have to get caught at the right angle to the wind for them to make noise, which at least for me doesn't happen that often.

I know what you are saying is true but it may not be THE answer. When I am on the highway I have pulled the door in closer (the door had already been properly shut) and that helps to eliminate a fair amount of noise. Further, I have manual doors and when I turn them really hard I can eliminate more noise too. So its not so much the vortex created in the bed or engine noise(engine is stock except chip). Ventshades are a nice suggestion but I find them ugly.

In that case you might could adjust the door latch strickers in just a little to tighten the doors' fit to the cab. If your weatherstripping is really shot or compressed, new weatherstripping isn't that expensive, nor too hard of a job.

IF yoiu have an older ranger then you'd probably benefit from either new door hinges or rebuilding door hinges.

As the hinges wear the doors sag and you loose tension against
your weather seals, this makes more wind noise than the vehicle was designed to...

What Robby suggests might help, but might not correct ALL of the problem.

I just rebuilt the hinges on my '87 ranger and it's FAR quieter than it's ever been....

But if you really have a problem with "noise" MAKG might be right you
are driving the wrong vehicle, might I suggest a Lincoln-LS?

this is one of the main concerns in a body shop when putting doors back on a vehicle after paint and bodywork.
robbie d is right in that the doors are probably not fitted correctly.i would check for worn hinges/missing weatherstrip.i guarantee the drivers door hinges have play but the weatherstrippings probably ok.open the door and lift up and down on the door to check play,if its under an inch or so its not to bad.
loosen the hinge bolts on the DOOR(not the body) and slide the door in so it will shut closer to the cab.look at the old bolt marks on the hinge to make sure its where you want it.you might want to put a shim imbetween the bottom hinge and the door to bring the door up if the hinges have sagged.
the body lines should be close between rear of door and cab and the latch should hit the striker square without jumping up or down to latch.then you might want to move the striker in just a little bit.
also if your trucks a beater like mine the upper window frame can bend away from the body as they are flimsy and let wind whistle.i opened the door and tweaked it in slightly at the top.
pickups are pretty noisy but your ranger should be relatively quiet like mine if its sealing air correctly.

Dude... just replace your weatherstripping... The rule is if you can close a dollar bill in the door and move it at all, the stripping is cooked.

 

[AllanD]

NOT necissarily.

If his HINGES are "Cooked" the dollar bill will slide even with new weather stripping.

Ditto for the plastic sleeve on the striker.

i agree if the hinges are too bad you need to replace or kit them.but most people are too cheap to replace hinges so i have gotten some pretty worn hinges to work on a lot of different cars at the body shop i work at.you can adjust them pretty far especially if you use a die grinder to slot the bolt holes which is why i suggested he just shim it up.its a light door compared to the explorer and if the hinges aren't too bad i'de just shim them.i've also seen some pretty old weatherstripping do just fine on the exotic restorations that come in like old lamborghinis,porsches,etc where you can't get easy to find replacements.if there isen't missing chunks or sections hanging its fine.the outer belt moldings on the doors(the seal the glass slides against,theres a felt one at the top of the door panel for the inside) can also contribute to wind noise if worn or the glass isen't up againt it tight.the same goes for the felt window track the glass slides in.if the glass is cockeyed it wont seat right.

 

[RobbieD]

Where is a good source for hinge rebuild kits?

I had the opposite results with Ventshades on my 2001. The cab was quiet until I put them on, and from then on out it sounded like I was driving in a wind tunned with the windows down.
