Very difficult to turn into parking space slowly

Hi guys, new to the forum...will complete profile soon! Question I have is I just added some 33x12.5 General Grabber 2 A/T tires...to me these have a very aggressive tread...most aggressive I've had. When I try to slowly pull into a parking space, or try to a sharp circle turn in a parking lot, my jeep basically stops...almost like the tires are grabbing so much that it won't let me turn. If I do the same thing a little faster, it's fine...is this normal? When I say slowly try to turn into parking space...like a normal speed you'd turn...when I say faster, maybe a little less brake...not much faster at all.

I did some searching in this forum and google and a few people talked about a bad Viscous Coupler? Not sure it's that as it was more about Cheerokee's than TJ's.

Any thoughts?

Thanks guys

Did you add new rims? If so, what is the backspacing?

You do not have a viscous coupler

yep, added some Ultra Crusher 15x8 - no idea though what the back spacing was - Town Fair installed them

Does it buck when turning?

Stuck in 4wd high on dry pavement would cause it to lose momentum when turning and not accelerating. The sharper the turn the quicker your momentum would die. A hard turn under power would/should cause severe bucking...without an axle disconnect...

My jeeps have always bucked like broncos on dry pavement but my kiddo switched my awd durango DD to 4wd lock a few months back and it drove fine in a straight line but couldnt negotiate turns without losing momentum and felt like it had a seized caliper or wheel bearing. Took me a couple turns to figure it out but it never once bucked...

*edited momentum instead of power*

Have someone turn your wheel from lock to lock and look for binding in the wheel wells or on suspension components...if you bind anywhere before full lock add washers to your steering bump stops to prevent it.

I dont see lift details in ur profile. You'll want to check specifically at the front sway bar at full lock. Also check the rear axle on both sides to make sure you are clearing the upper spring perch. An uncorrected lift will cause the axle to shift to the passenger side and shove your tire against the spring cup.

Do this immediately as you will chew through the sidewall in short order if you are rubbing anywhere...

it bucks at very slow speed turns, like 5mph or normal turn into parking space speed...if I turn faster, say 10mph it is smooth.

if it was in full time 4wd wouldn't there be a light on telling me that? or the shifter be in an upward position? right now there is no light on and it's flat against the floor.

Does it buck in slow speed turns if you don't touch the brake pedal?

Find some place you can test that. Empty parking lot or similar. Do a slow speed turn with and without using the brakes. Report back.

Akwardness turning at slow speeds is a pretty typical sign of having drive delivered to the front tires (either in 4WD or FWD). Ideally yes, your light would be on and the handle would be up, although it is conceivable to happen otherwise.

I'm thinking your new wheels have too high a backspacing and so the much wider tires you put on are rubbing on the control arms when you try to turn. At faster speed there is enough momentum that you don't really feel it, but when going slow you do feel it.

I will do this tonight and report my findings...really appreciate the feedback.

We have a part time 4wd system.

The bucking will occur when under power and in gear. If you are coasting into a space out of gear you wouldnt notice it but you would lose momentum. Also 5 mph is pretty slow. At such a low speed in say first gear things could get a little jerky as small changes in acceleration makes torque...

I wouldnt assume the dash light works. The shifter handle should indicate your 4wd position however, i installed a cable shifter on my tj a few months back and due to the cold weather i never tweaked its shift throw so a small tug on my shifter engages 4wd high. Im not saying thats what is happening here.

Before we go down that rabbit hole check your backspacing and tire clearance. Its the most likely culprit...

My money is on the exact opposite. They installed a shallow backspaced rim and the tires are far enough outside "correct" scrub radius that they quit rolling in a turn when the brakes are applied.

It could just as easily be what you are saying though.

makes sense! how can I find out if it is indeed stuck in 4wd?

is there any chance it could just be as simple as the tires are really "grabby" and at slow speeds it's difficult to make a sharp turn?

I'm going to go with the most accurate theory when it comes to problem solving which "it's almost always the last thing you touched" right before you noticed the issue. In this case, not 4wd related because that would have been a problem before the new tires and rims.
