Re: Project DD moonlighting as trail rig - *insertusernamehere* - 07-14-2015
Wheel bearings on both my previous cars were bad with no wheel movement. I suppose its time to park when you do finally have wheel movement? It's most likely not a big deal, yet, I think jake ran the M3 with a bad wheel bearing for quite a while, yes?

Just because I did doesn't mean you should. I was stoooopid. It started making noise in like, June of 2014. I finally said "enough" after the October '14 VIR event and let the car sit, until I paid a shop to do it in January of 2015.
I didn't have any play when shaking the wheel up/down or left/right (it was a rear) but it made a nasty wubwubwub sort of noise, that got worse when I loaded up that corner (i.e. turning one way) and got better when unloaded.
I wouldn't worry just yet but keep an eye/ear on it.

this is exactly how my passenger rear bearing went bad on my impreza. the noise changed depending on if i was turning left or right (loading and unloading) and only after checking a few hundred miles later did it actually develop any play at all when i'd try to shake the wheel with the car up in the air. when i replaced it the noise disappeared so it was definitely the bearing.

Last time I had to do a wheel bearing it sounded like I was being chased down the highway by an Apache attack chopper.
Re: Project DD moonlighting as trail rig - Senor_Taylor - 07-15-2015
It definitely changes based on which way I'm turning. I appreciate the advice, guys. That's the price I pay for my wheel bearings basically living in mud. As long as it'll last until I can get back to JMU, I can drive my Miata until the snow comes in.

Unbalanced wheels/tires or non-uniform wear with tires can translate vibrations/noises that you wouldn't point to being wheel/tire noise.
Report back after Thursday on status of noise.
Re: Project DD moonlighting as trail rig - Senor_Taylor - 07-16-2015
Well, got the tires rotated today and the sound seems to be coming from the rear now. I can't tell if my ears are playing tricks on me or what, but if they aren't, that means ones of the tires is wonky. The guy at the shop said that the front is "tight", so that's good, I guess.

Sounds like one of your tires is indeed "wonky". Uneven wear will definitely cause that.
Re: Project DD moonlighting as trail rig - ScottyB - 07-17-2015
maybe one of the belts inside the tire is snapped and its only getting partial support from the internal structure on part of the tread. it happens, though not very often.
Re: Project DD moonlighting as trail rig - Senor_Taylor - 07-17-2015
With the abuse my tires take occasionally, that seems plausible. I'm not really worried anymore, it's just extremely irritating. It's such a high pitch noise that it starts to grate on your ears. My sub usually drowns it out, though. My tires are near their end anyway, so they'll be replaced after this winter. I still haven't decided on what type of tires I want. I really want a true 33", but I don't think I can fit any without rubbing unless I go the 245 route, but those are extremely hard to find.

My thoughts.. My gf's Mazda used to make a "wompwompwompwomp" sound at low speeds with a slight shimmy @ 60mph. We bought new tires and that all went away. I'm pretty sure one of the belts was jacked up from all the potholes here in NOVA.
Re: Project DD moonlighting as trail rig - Senor_Taylor - 07-26-2015
For those of you who may remember, I at one point installed a 65 Watt PA speaker in my grill and had it hooked to my amp. Well, I blew that. I always assumed it was because it was full of ice, but it may have also been from the fact that I was running it on a 650 watt amp.
I just ordered some 200 watt marine speakers and I'm wondering if I'll end up blowing these as well? I figure if I have them hooked to one channel and my 10" sub on the other. It'd only be ~325 watts to each channel and it'd be fine if I didn't run them too loud? I know nothing about car audio at all. I guess I should be fine because I've been running my 200W sub on it forever. Anyone know?

Re: Project DD moonlighting as trail rig - Sully - 07-27-2015
It's depends on the ohm load and how your amp handles the channels and if you have it wired correctly in the first place. And if the numbers you have giving are peak watts or rms watts. Do everything by rms watts because that's what it's actually producing most of the time. And you can probably be a tad higher than rms. But don't just hook it up and assume you're going to be getting.
Also, you're kind of doing it wrong if you have a two channel amp getting a signal from the head unit on the speaker output and running a sub on it depending how your head unit outputs the signal. If it's only sending frequencies above like 120, your sub is not really doing anything for you.
Now I mean if you don't care about longevity of your speakers or sound quality and just want something that is loud and vibrates, You don't really have to worry about anything I've said

So, yeah.

Thanks for the reply, Sully. My head unit has a cross-over menu where I can choose which frequencies to send to the amp. My sub has a response range peaking at 120, so I usually have it set to play everything under that. The sub is hooked up properly. I used to have it bridged and it sounded very nice. Now that I've wired these two speakers into the other channel (wired them in series), the sub doesn't hit as well as it used to. Oh well. It's very convenient, though. I just flip the low pass filter on the amp "on" and the speakers in the grill don't play since the range isn't low enough. Not sure if that's going to hurt them or not, though.
Re: Project DD moonlighting as trail rig - Senor_Taylor - 01-10-2016
I bought some 15" Toyota steelies from Colton's friend a couple of months ago, and I got my Eibach 3" lift springs to complete my lift for Christmas (It only took 2 years). When I get my tax return, I'm going to pick up some BFG ATs in 33x10.50x15 and get them mounted on the wheels.
What's a good shop in Harrisonburg to get my bilsteins taken off and have the spring seat adjusted to the "No lift" position and the stock springs swapped for the Eibachs? I'm NOT doing this job myself because it requires a lift and a spring compressor. I figure it shouldn't be more than $100, hopefully. Preferably, they could mount my tires and put them on and balance them as well.

Well, my truck started hesitating under load. I cleaned the MAF and ran seafoam. Only made it worse. If I floor it, it will rev up and then afterfire. Funny thing is, if I rev it by hand, it's fine. If I rev it with the actual throttle pedal, it cracks up and doesn't rev properly. Could be plugs and wires, I guess. I'm supposed to drive to the beach in it tomorrow morning, so I guess I'm taking the Miata.

Same with the throttle position sensor. Is it only happening at high rpm?

What's with the seafoaming of everything? Its not some miracle potion.
Was the truck driving fine yesterday and then all of sudden hesitating today? When its something sudden like that, its usually something electronic. If afterfire = backfire, then some fuel isn't getting burned properly. Maybe you have something wrong with the ignition (spark plug or maybe wires/coilpack?)

Side note on Seafoam:
There's been a lively discussion about GDI engines and catch cans on the twins forums. An engineer that works at a consulting firm for a number of the major manufacturers, who literally tears down coked up DI motors all day long and designs systems that address it, said that you should never do a chemical upper intake cleaning of a DI motor. It causes the deposits to break up only partially and the fragments score the crap out of your pistons and cylinder walls, possibly bend your valves and 100% lead to engine damage. Here's what this actually looks like after one of these dealership-administered cleanings:
![[Image: valve%20bent%20by%20coking_zpslokaym2f.jpg]](http://i1083.photobucket.com/albums/j392/tech17/valve%20bent%20by%20coking_zpslokaym2f.jpg)
I have never done an upper intake "sip" method of Seafoam only poured it in my gas tank to keep the injectors clean but I will definitely not be doing this now, ever.
And I know your truck's engine was probably before DI's time but I dunno if you could have the same issues doing this on non-DI vehicles
Re: Project DD moonlighting as trail rig - Maengelito - 06-24-2016
yeah, I think that's more of an issue with DI engines since you don't have the fuel coming in through the intake valves but its certainly not only DI engines. I think if you do some basic maintenance, change your oil regularly, and floor it every once in awhile, you probably don't have to worry about deposits like that. Regardless, I doubt this is Taylor's issue on his truck or his Miata.
