hey gang my jeep is on a 4 inch lift with 33 inch wheels with a 5 speed manual 4.2 inline 6 now the problem is I cannot use 5th gear one guy said upgrade the front and back differential cost 600 bucks andother guy say cut a plate cover on the tranny so the shifter can reach the gear ?? HEEEEEEELLLPPPPP!!!!!

[BlackOpsPete]

Is it interfering with the floor pan? If so cutting the hole a little bigger will help. Do you have alot of slop in the shifter? If so there are ways to tighten it up which shortens the throw a bit.

Differentials have nothing to do with shifting into 5th...

[calderman87]

Are you trying to say you don't even use fifth gear because you can't get there with your current set up? Or are you saying that you physically can't shift intothe gear because it pops out or won't engage etc? Of the first then you may want to consider regearing your axles, if it's the latter you may consider cutting a little of the floor board to give you room to shift. Need more info to be of better help.

Need more on the specific problem... Sounds like you don't USE 5th as it will not hold speed on the highway, more H.P. or re-gear the Diffs is the answer. BEEN THERE... if 33's are what you are going to run for a LONG time, 4.11's in the diffs should work to keep a little HWY power and the RPM'S in a Happy Place at Hwy speed. If it's Dana 35/30 combo any bigger on the tires will probably mean an axle upgrade... My 4.2 came with 115 H.P. and 3.07's in the Diffs.

hey guys thanks for the reply and the answer to the ? is yep I shift to 5th gear but cannot accelerate when I go back to 4th I am able to speed so yep its like I cannot u 5th

Tire size? Stock gear?

If you have larger tires you effectively have reduced your gear ratio. Welcome to jeep modification 101.

How much does it normally cos to regear I have a similar problem... I have an 01 tj with a 4 inch lift and 35s also I don't want to lose power in my low gears

It depends on if you go with a locker while that have it out. I have a 02 with the 4" and 35" i run 4:56 gears and used to make the trip from Homestead to Ocala every weekend for a year.

[ebenk17]

How much did you pay?

What axles do you have now, if it's a D 35 in the rear and are considering an axle change, an 8.8 from an Explorer is a good choise... there are a TON in the junkyards, I saw 5 in the U-PICK-IT my last outing, you can find them with 4.10's and disc brakes, will run about $100.00 at the U-PICK-IT just need to put 1" spacers on your wheels as they are about 58" wide, not sure of the bolt pattern to fit YOUR rims. If you look hard enough a limited slip came in some.

? You can put axels from a ford explorer on the jeep? intresting but would i have to change the shifter as well from my tranny

[Big Red One]

A lot of people change JUST THE REAR to an 8.8, it's a very cheap upgrade, better brakes, stronger axle and a limited slip, the shifter will not be affected.

damn i gotta educate myself on this better lol

[JBYDesign]

Yeah 8.8 is one way to go... or just find a set of used 4:10s and swap them in... they were on all of the 4 bangers with manual 5speeds... it will cost you about $100 per axels if you go with new bearings and seals...

I already picked up the gears... but will have to wait until my tummy tuck is done...

Oh forgot to mention that Log bouncing is not reccomended with the 8.8... yoke at the diff tends to snap!

If you looking to just bolt in better gearing the 410s axles out of a 4 banger are the ways to go. Axles can be swapped in a day. The 410s will drive 33' tires and you'll like the obvious difference.

The Ford 8.8 is a much better axle as noted above but you will need to do some welding of spring perches and a custom drive shaft at a minimum. So that is something to consider. If you plan on going crazy with the rig then doing it right the first time makes sense but only if you can afford it.

Re-gearing can cost anywhere from about $300 to $1200+ per axle depending on what you go with - used or new locker or open carrier. The D30 (front) and D35(rear) have a "carrier break" and you will likely need to get new carriers to go with your new gears like the 410s. I included the carrier replacement cost in the numbers above. You also will need seals, shims etc.

If you're not totally familiar with what's involved you will need to do some research and or get help.

I'm not planning on going insane with it i just wanna be able to use te 5th gear and spare the egine some stress when i drive on the free way I think 4.10 axel swap might be the way ta go and nope i aint totally familiar with it but i am learnng everyday lol ooh boy
