Couple pictures and questions

[Jason4x4]

I got my 32" BFG Mud Terrains yesterday and got them mounted today. Here's a couple pics. I have a couple questions - The guy at the tire shop where I had them mounted/balanced said I needed to regear to 4.10s because running 32s would "slowly burn up the syncros in the transmission". Is this true?? I mean, I imagine it would slightly increase wear running the same gearing on bigger tires due to the fact that the motor will have to turn faster to make the same speed as with the smaller tires, but will this cause my "syncros to burn up" just because of the extra mass?

Also, they rub a little bit on the swaybar, but only under full lock and if the suspension is compressed (i.e., if I'm going really slow so that the springs don't really compress in a corner, it doesn't rub). Is there an easy fix to this? Is it something I should worry about? I mean, I know I could get a bigger lift or wheel spacers, but I dont know that the benefits would be worth it. Is there any other options I dont know about (trying to minimize costs, of course). I'd appreciate some input. I didn't really plan on going bigger than 31's right now, but I couldn't pass up these tires with less than 1k miles (still have the 'nipples') for $350.

Here's the pictures:


P.S. I know I need a 5th tire for a spare .

You can do a small budget boost lift which usually costs around 200 bucks. Tires look good on there though, I think it looks good like it is. You can also adjust your steering stops slightly to keep you from rubbing, but then you lose a touch in turning radius.

As far as the synchros, the guy is an idiot. The only time the synchros see use is when you're shifting. They are there to slow the gears down while you shift to the next one and only see use (normally) when the clutch is in. There is no extra rotational mass added to your transmission that would cause an excessive wear of that manner. However, harder use with larger tires can cause transmission failure, but not synchro wear. In fact, the larger tires slow down the RPM's of your engine versus your speed because they travel further on one rotation of the gears versus the stock tires.

Point in case, the guy at the tire shop is an idiot, and there's a reason he works at the tire shop.

Thanks for the info. Can you tell me exactly how I would go about adjusting the steering stops?? I don't think the rubbing is going to be a major problems, but I'd like to know how to adjust it in case it turns out I'm wrong. And by the way, I already have the 2" budget lift installed .

Those meats look good!!!!! (except for the spare, of course :lol: :lol: :lol: ). Currupt gives good advice........the guy at the tire shop knows tires, not transmissions. Go get 'em muddy!!!!!

If you get down on your front axle and look at each steering knuckle, there should be a little bolt screwed into it that contacts the axle when turned. Just adjust that out a little bit until you are happy with it.

It is on the front of the axle, on the lower part of the knuckle. I've never taken one out so I don't know if you can just adjust it or if you need to space it or what, but it needs to be locked in place, so figure a way to do that. This was a picture I found showing a guy who took it off and spaced it a little and then put it back on. Do it for both knuckles (I think there's one on each).

By the way, really like your Jeep. I need another one for a daily and that's exactly what I want. Wanna buy a Jetta?

The transmission has a torque converter and that is the purpose of it (keepin' the 32" tires from "Burning" out the syncros).

You could live with the swaybar touches, but Currupt4130 does give you some excellent advice.

As you said, I am much more worried about the spare. If you need to use it, it could cause problems. Try to find a spare with about the same amount of wear as the other tires. Rotate on schedule!

The tire shop guy is 50% idiot.. yes mis-geared axle and tire combo's can prematurly wear out components on your jeep such as the clutch, and perhaps your brakes (more use of brakes and less down shifting sue to less engine braking) but your syncros are not one of them, and I would not worry about 32's on stock gears. If you ran 35's or 37's then yes, regear would be a little more needed, but 32's Nahh

Steering stops.. never adjusted them, I would just listen for the tire rub and then turn the wheel 1/16 in the opposite direction, usually only in parking lots and wheeling so slow speed never did a whole lot of damage.

IMHO, I would not sweat it.. as for regearing, if you drive it minimally on the highway, go deep or go home.

The most highway driving it sees is about a 300 mile trip each way when I go home to see my parents - and even then we usually take my fiancee's car. And that trip is only usually made once every couple of months. Occasionally though, like this weekend, I have to take the Jeep. I'm not real worried about the rub. Thanks for the comments and info guys.

When did manual transmissions get torque converters?

 

[cewtwo]

Sorry! I saw synchro and assumed an automatic transmission!

It's ok, we can't all be perfect [/sarcasm]

Sweet ride! Do you have any lift at all?...What year TJ is that?...very cool though...

I have a 2" RE "economy" (i.e. spring spacer) lift. It also has the Rubicon springs as part of the 'heavy duty suspension' package I ordered from the factory, which I'm told actually gives you another .5" of lift compared to non-Rubi's without the heavy duty option. And it's a 2006, just over a year old. Thanks for the compliment .

Re the steering stop picture: That is a bolt threaded into the knuckle with a jam nut. Back the bolt out, then tighten the jam nut.
