Front End Alignment After 2" Spacer Lift?

I am just getting ready to install the 2" Rough Country Lift on the '08 Commander 4x4, just one quick question. Do most people need an alignment after the install on the front tires? Is it possible I won't? I'm guessing I probably will, and if so, will it be manageable enough to at least drive a few miles to the tire shop? And how exactly would I adjust the toe in or out if it was pretty out of whack, so I could at least get to an alignment shop? Thanks in advance, I can't wait to get em on! The spacers are just sitting in a stack in my living room, taunting me

Yes, you'll definitely need an alignment. Any time the front end is lifted (or lowered) the geometry changes and the alignment gets everything back to factory specs.

You shouldn't have too much trouble getting to the shop, though I wouldn't advise driving on the highway. Take back roads where you can keep it below about 40 or so. The toe won't be the issue; the camber will be off with the tops of the tires further out than the bottom. Toe will need adjusted too but won't keep you from driving it.

Yes a four wheel alignment is recommended.

Why a four wheel alignment? On most vehicles with a solid rear axle, there aren't any adjustments available for the rear tires.

You have a good point here. I had a 4 wheel alignment done on mine after shocks, bushings, end links, etc., on all 4 ends. For me it was as much piece of mind on a new to me WK with 95K miles at the time. I can say I am very happy with the way the vehicle tracks down the road in all conditions.

I've only ever had front end alignments done, but I've had most of my rear suspension completely apart and saw no adjustment points, so I was wondering if I had missed something.

I don't object to getting a four wheel alignment if it gives you peace of mind, but I think they may be charging for a four wheel alignment while not adjusting the rear at all.

Actually not true about not needing 4 wheel alignment. The rear axle can shift out of place. Results in a condition called dog tracking which increases tire wear and costs fuel economy. Tires are expensive, why risk it.

I am curious about this also. The tire shops always "recommend" a 4 wheel alignment and as someone said earlier - what can they adjust in the rear? If the rear axle "shifts out of place" - how is it adjusted back?

Generally you loosen all the mounting hardware and physically shift the axle. A vehicle dog tracks because the back wheels are further away on one side.

I bought a 1989 Ramcharger many years back that had it quite noticeably. My brother and I jacked up the back and used a winch the pull it back once all the fasteners were loosened. Once the distance on each side was measured to be the same, we torqued all the mounting hardware.
