99 hoe bogs down in mud??

[felskee]

well when i go mudding and need to reverse it bogs down. not losing rpms or anything it just has no power and it stays at a certin rpm. put it to the floor no change. in drive it does the same until you get on it then its not that bad. im thinking it has to do with the gears? 3:42 on 33

Might wanna clean ur throttle body. I would also look at getting a tune up ajd does ur hoe have lockers?

 

[felskee]

its a brand new motor less than 10 k and nope

you reverse gear ration is probably playing the biggest role in that although 3.42 gearing may not be helpful either.
1st: 3.059
2nd: 1.625
3rd: 1.000
4th: 0.696
Rev: 2.294

you only get one reverse gear ratio unless you kick in the low t-case gear.

and when im on pavment from a dead stop its kinda boggy wierd feeling till about 10 mph

i hope its just the gearing

 

[SunlitComet]

have your tranny line pressure checked for proper readings. to high a reading can do that.

 

[felskee]

where would you have it checked

 

[SunlitComet]

any reputable tranny shop. they have the equipment ans specs on hand.

33's, 3.42's and mud. You do not have enough gear for the tires as is, and when you throw mud into the equation, it only makes it worse. Needs more gear IMO

I had 3.73's in my Tahoe with 33's and thought that I did not have enough gear. Mine would bog sometimes if I got into something deep or when climbing rocks

gears i think are to blame here you have to equate the weight of the mud itself soupy mud acts as a suction on your tires thus slowing it down slap 4.56 under that bad boy and hold on the engine doesnt have anything to do with it as v-8 provde enough torque , take a lesson from a 4cly jeep with 35 or greater tires all they do is regear

 

[purple 'hoe]

I agree, 4.56 if you are going to keep 33's

 

[SunlitComet]

seems a bit much. Felskee what tire size was stock on your vehicle?

 

[purple 'hoe]

I'm assuming he uses this truck often for mudding if he is bogging down in mud.

You want to regear for your terrian and your tires when it comes to off roading. 4.56's+33's (op stated 33's) would be good for a mud set-up. It might suck on the street, but theres no fair trade off here

Could maybe run a 4.30 if that's available for his truck. Not sure if it is however

Check the fuel pressure that might be making it bog down.

Ive done a TON of mudding in my truck and i can assure you if its only happining in mud its gears related , purple is right here with the no fair trade off , while you will notice a def increase in torque and feeling of power and wheel spin . gas mileage decreases with a regear . mine does it all the time since i have not yet regeared 4.56 is a bit much for 33 as its a near perfect match for a 35 but if you mud often im sure you are thinking of lifting and bigger tires in the future 4.10 gears would be OK also for 33s but you will run into the same issue once you go to a 35, use this chart http://www.offroaders.com/tech/gear-ratio-chart.htm , remember i said 4.56 almost perfect for overall.
lets just drop a 5.71 ratio under it with 44s =)

 

[purple 'hoe]

Or we could put some rockwells under it with 6.7something gears. No issue of ever bogging down again lol

Well i use mine as my dd since im still in hs lol. I plan to get some 35's soon but moneys the issue when it comes to the damn gears, been quoted 1500+ for front and rear and stock size tires were i think 265 .... 15

And yes i eas looking at 4:56 for my futre 35's

 

[SunlitComet]

if your stock tires were 265/75/15 and current gear is 3.42, the when you switch to 35 you would need a 3.91 to re equal the given RPM in Feet Per Minute. this would basically return the stock rwhp to ground but does not take tire mass into consideration on acceleration rate. if this is a vehicle that sees any road time then i would suggest 4.10 for street and using the transfer low modes and gear 1, 2 or 3 for mudding. it is the compromise that seems to make both sides of equation happy for power and mileage.

if you have different measurement you want to try let me know.

 

[felskee]

well i dont want it back to stock... hahah i cant stand this sluggish / no power. thats why im saving up for some 4:56s to get put in for a steep 1500..
