Impact wrench

Is an electric Impact wrench enough to get the yoke nut off to change a pinion seal? I don't have air tools and I was thinking about getting an electric impact wrench.

Also if I did get one what are some other things it will come in handy for on the jeep? Thanks.

the one I'm looking at is

1640/2440 ipm 120v 60h 8.4 amp

A good cordless impact like Milwaukee or brand name will cost some coin $$$ check price vs air compressor & tools.

I used a Milwaukee one when I did my lift and had a real good battery for it as well. It lasted for a complete day of wrenching, but it did cost me some coin

You can do better than that price for sure.. Any of them should do the trick, May want to check your local rental places as well, and just rent a small compressor and impact.

Thanks guys, I will check around. For an electric or cordless what type of specs should I look for that would suit me well for all use on the jeep. torque, voltage, etc... I don't know what to look for.

Another option is to set the ebrake if its the rear axle, or have someone stand on the brakes for the front axle and use a breaker bar to bust it loose by hand.

^ that's probably what I'm going to do thanks. I read something about putting it in 4lo for the front as well will that help? How handy is it thought to have a cordless impact wrench when working on other things? worth the buy?

Theres a rental place near me so I might just rent one for $10 a day, just need to know what to rent power/torque wise.

You might also need a pry bar for helping break the Pinion Nut. It will help so the yoke won't spin as much. Be prepared to wrestle with it and then make sure you tighten it back to the proper torque as well, I believe 160-180.

I would stay away from the Harbor Freight one. Made in China junk, more then likely it wouldn't last very long and personaly I despise anything made in China. They are getting filthy rich by selling us all their garbage!

I would ask the guy running the rental place what he suggests if you go the rental route.

I think I'm going to try and have someone step on the breaks and wrench it free it can't be that hard right? If worst comes to worst and I can't break it free I'll go rent an impact wrench.

Do I need a puller to get the pinion out of the diff to get to the seal?

You'll want the impact gun, trust me, there's not much room under there to try breaking it free by hand or breaker bar.

Nope no need for a puller, it should slide off the splines, maybe just a little tap to break it loose.

Did you find one of the write-ups for this????
it will help greatly. If you have the D30/D35, there's a good chance you'll need crush sleeve washers/spacers for tighening it back down for proper spacing.

Mark or measure the distance on the yoke as well, to help with re-installing.

I haven't found a good write up yet but I have done some research on the basics of what needs to be done. From what I have read and the people I have talked to It's my understanding that all I need is the seal and a new pinion nut (suggested I don't reuse the old one). I have the seal and the nut already for a d30 and a d35 both are leaking. I was told I don't need to worry about the crush sleeve as long as I don't over torque it. The write ups I have seen pull the DS, the pinion nut, the pinion, pry out the seal, tap in a new one and reinstall everything and torque the nut to around 180.

You can also consider a Hand Impact Wrench. Sears has one for $25. Yes, it's slower, but if your just trying to break it free it will do the job. Also since it does not need any power, it works on the trail too.

I have a "Harbor Freight" electric impact wrench (corded) because I don't always access to air, it has been a life saver, have not used the battery operated, but everyone that has has told me go with Milwaukee or another tried and tested brand....they are not all created equally.

I managed to get the pinion nut off a few times with a long breaker bar before I got my air tools. Chock the tires, put it into 4x4, and into gear so the front axle can help hold the Jeep from rolling as you use the breaker bar (HFT has them inexpensively) to remove the rear pinion nut.

I'm going to save myself the aggravation and just rent an electric one, it's $10 a day.
Anyone have a good write up for a d30/35 or any tips? is it necessary to mark the pinion and yoke to get it back on correctly or does it not matter?

Also I read all this stuff about setting the bearing pre load because the d30 has a crush sleeve and measuring rolling torque etc... all the write ups I see people just replace the seal and torque it to 180ft/lbs. Can someone who has changed a d30 shed some light on this?

I did my d30 recently. Rent an impact wrench for removal trust me. Now what your supposed to do and what I did are two different things so I would advise against my advice even though it has been working for me just fine.

I removed the DS, removed the pinion nut (I marked where it was on the pinion with paint and I also counted the threads showing before I removed it) removed the pinion. Scraped out the old seal with a screwdriver. I cleaned up the surface of the yoke that the seal rides on, cleaned up the inside of the diff where the seal sits. I put in the new seal with a block of wood and a hammer (if you don't hit it in evenly you will mess it up) reinstall the pinion, yoke, then the nut. I put it back to where I marked it with the same number of threads showing then tightened it just a hair more. Has been working fine but I'm sure people will say my pinion bearings are not loaded properly and will fail in x amount of miles which there probably right. Alternatively if you don't mark where the nut was which I forgot to when I did a D35 I just torqued it to 180ft/lbs.

the right way which I don't have enough patients for is to remove the wheels and pull the axle shafts enough to disco them from the side gears then measure in INCH pounds how much it takes to turn the pinion. Most people make this job into much more than it needs to be, I know many people who just crank it down to 180ft/lbs and call it a day. It will probably wear the pinion bearings much faster but who knows.

Not suggesting HF but I bought my HF corded impact for $30 knowing it would die an early death...I'm actually surprised it is still working today (going on 3+ years), I use it all the time to remove my lug nuts and recently on my lower control arm bolt to install my engine skid. I bought a cordless Sears 500 ft lbs impact in anticipation that the HF would break but I haven't used my Sears yet.

Lol....

changed my pinion seals about 2 weekends ago and couldn't stop the differential from turning, even with someone standing (literally) on the brakes, E-brake full on after tightening. Not enough clearance to operate (or put enough a$$) a torque wrench under jeep with wheels on the ground either...I think it was 210 ft. lbs but anyway I couldn't do it. Impact gun all the way

So you used the impact to put the pinion nut back on? What axles do you have? everything I read says you have to be very careful putting the nut back on but I'm getting the vibe from this thread that its nothing to stress about. Can I put the nut back on with an impact? Won't that be to much torque?

bump...would it be a bad idea to just torque it with an impact wrench or if need be to 180ft/ibs without measuring the rolling torque? Would that screw up the pre load?
