FSJ Nut buys 93 Wrangler, has lots of questions..

I can wrench and have a Jeep J10 that I've adored for years. The 360 needs a top down rebuild and a transfer case rebuild and 99% of you know the stork does not drop $4k down the chimney...

SO I bought a used 93 Wrangler. 4-cyl. 69K miles. 5 grand. Engine and tranny are healthy and responsive, as is the New Process transfer case. I waited with my saved money and waited for the right deal. I do not feel cheated. I bought it from a very rich person who babied this thing.

I used to think until someone experienced a FSJ, they did not know "Jeep Thing." But I am wrong!

I'm a newbie. I like this YJ and intend on being around for a while. You guys are extremely knowledgeable.

Here's my questions:

This thing is a death-trap over 50 mph, right? I commute 100 miles a day from 3500 feet to 7,000. (Rimrock to Flagstaff, AZ).

31X10.5 New BFG's. Why don't I feel confident at normal speeds? Will I?

I think have an AMC engine? Please confirm so I can feel happy. (I trust them more than Chrysler and know how to work on them).

Can I put the Wrangler in 4WD on icy roads? I hear SO MUCH talk about being insane to put a Wrangler in 4WD on pavement. Well, I need to stay alive so I guess this is the most important question.

I've driven an outdated Jeep dinosaur, self-restored, 3 tons, for the last 7 years and every second has been a pleasure. I'm looking forward to increasing my carbon footprint once again...(heh).

I'm a noob. I'd ask for kindness but I know how things go...My name is Brent...looking to get these 4 questions answered and I got a bunch more. I have a fine Wrangler but I dont know much about it.

Welcome ,pics?
If you are running 31s I am guessing you have a shackle lift
You should be confident to around HWY speeds
might take some time to get there

Yes on the 4WD just not dry cement


"locked and loaded"

Thanks for the immediate response on the 4WD question. But a more or less maintained federal interstate running through different counties is either ignored with ice and snow, heavily cindered, or perfectly maintained. Can I freeway drive in 4WD in all these scenarios (which are daily) or is it good policy just to shift on the fly as needed? Have no clue the capabilities of the the NP T/C.

Uploaded a pic within website pixel instructions but still can't post it. A different thread tells me I have to start an account at a pic website. Too many mixed messages. Have pic, can't post, will figure out. 3" lift shackle to answer yr question. Thank you again, Birdhunter.

Hi Brent! Welcome to the forum. Its not generally a good idea to run part time 4wd on dry pavement. Your part time 4wd system on the YJ was not intended to be driven at high speed (over 50). Your J-10 had a quadratrac full time 4wd sytem and is different. When you put your YJ in 4wd the front will bind up the sharper you turn the wheel. With part time 4WD your front wheels are forced rotate faster than the rear when you turn. Since the front drive shaft turns at the same rpm as to the rear there is a binding between front wheels and the rear. The front drive shaft in effect tries to slow down the front wheels. This isn't a problem on dirt but on dry pavement this will cause control problems.
Please post up some pictures of the J-10.
Nothing is foolproof to a sufficiently talented fool.

you should be fine at highway speeds, i have an 87 yj with 32's and i can cruise down the highway no problem, it handles fine, i have gotten it up to between 65 and 75 with no problem doing down the highway so you should be fine as long as the 4 cyl can get up there as it will take a while, if your jeep feels anything like mine it feels like you are moving faster then you are but you will get used to it and become more comfortable with it the more you drive it

i-17 will tear up those bfg's.and they will vibrate like hell. for 100 a day i'd go with a different tread. maybe some goodyear wranglers for the highway and keep the bfg's for the broken arrow. i drove for a day in the west and adventure co, in sedona, and have had some experience on the roads you drive. contact me any time.

That I will get more comfortable and currently feel I am going faster than I am makes me feel a hell of a lot better. I honestly didn't know if it was a 'mind' thing at first...it is!

Hey Navy, thanks for the reply. I just bought a brand new set of Hankooks for the J10. I'm fond of that brand and might put them on the YJ this weekend.
I-17 sucks in winter and it is winter. But 89A from Sedona to Flag is safer passage.
Thanks for the offer to contact you---I still have a lot of questions about the YJ.
