wheelbase affect...

I just measured the wheelbase on my 2000 se TJ and it is right around 92". I read that stock wheelbase is 93.4".

My question, will a shorter wheelbase have any affect on ride quality?

I have metalcloak control arms in front and getting an alignment tomorrow, so I can have them put it back to stock wheelbase.

Thanks for any input

Everything else being equal, shorter wheelbase usually comes with a harsher ride. I don't know how noticeable 1.4 inches would be, but I think you're on the right track with putting it back to the stock WB.

A shorter wheelbase is going to have a poor ride quality. It will be choppy, the rear will bounce around more and will be quicker to spin around in slick conditions.

The difference is absolutely negligible.

If you restore your wheelbase back to 94" at ride height, what will happen at full bump? Just something to think over....

Lastly, I wouldn't trust the standard monkey at an alignment shop to know how to properly adjust control arms and position axles. Unless you find a very rare specimen, I'd leave that up to you and your tape measure. On that subject, I'd leave the entire deal up to you unless you have absolutely no mechanical knowledge at all.

I am trying to learn as much as I can. That being said, this is the first vehicle I have ever done maintenance on, so my knowledge is on the lesser end when it comes to my TJ. Suspension geometry and componentry are intriguing, but I know little about it all. I am assuming that restoring wheelbase will not affect anything at full bump? Is that what you are getting at?

As far as finding someone to properly align everything, I am taking it to a reputable 4x4 shop in town, who is also a vendor for metalcloak, so they should know how to adjust everything and set me up right. Hopefully...

Thanks for the input

It will affect things, your diff will be all up in the gas tank. Decreased wheelbase because of the lift is a factor of geometry, not arm length. Imagine the axle at full bump, there not a lot of room between the diff and gas tank, if you increase arm length your pushing the axle into the gas tank.

I have adjustable ca's in front, upper and lower. Rear ca's are stock for now
