Pls clarify the "garage" jack points for Leaf -

Wed Oct 03, 2012 9:24 pm

Hi,

Sorry for the long post.

I want to send my Leaf over to Wheelworks to rotate my wheels for me. Since Wheelworks isn't a place that is knowledgeable about the Leaf, naturally, I have decided to read up a bit on the Jack Points or "garage lift points" or "garage jack points" information so that I can explain to the wheel/tire technicians how to hoist the car up properly.

I suspect that the Jack Points http://nissanleafwiki.com/images/2/2f/P5033631.jpg" onclick="window.open(this.href);return false; isn't the main location for a commercial place such as Wheelworks to hoist up the car.

At places like Wheelworks, they don't typically hoist the vehicle up at the usual "jack points" that the customer would use to jack the car up to replace a flat tire. The shops have these hydraulic jacks with 4 circular "cups" at each end of an "X" beam where they position at the 4 corners of the vehicle. If they are indeed using the Jack Points location, should they still use some form of a "wooden block" that Andy Nguyen (aka: aqn) talks about? I can just see if not using these wooden blocks, that they will surely damage the metal "pinch weld" at the Jack Points.

Furthermore, I continued to research "garage lift points" or "garage jack points" information but found conflicting information. Andy Nguyen (aka: aqn) has good pictures and the links....

What I have found so far:

1) A picture that is apparently in-accurate for lift points. Picture shows exhaust pipes, probably a misprint of another vehicle other than the Leaf.
https://docs.google.com/file/d/0B_0onPG ... edit?pli=1" onclick="window.open(this.href);return false;

2) There is a discussion thread here: http://www.mynissanleaf.com/viewtopic.p ... 58#p174658" onclick="window.open(this.href);return false;, but still very confusing.

3) Wiki http://mynissanleaf.com/wiki/index.php? ... _up_a_LEAF" onclick="window.open(this.href);return false; does not explain what to do if you are sending your Leaf to a commercial wheel/tire shop who doesn't know about these cars and the Owners Manual with wrong information of garage lift points is useless.

Any advice is most appreciated!

Auto shops will simply lift the car using those pads under the seam lift points. No blocks or anything. As long as they are lined up OK, everything will be fine.

you have nothing to worry about. using those big round cups as jack points reduces the pressure on the jack points. regular home jacks put the entire weight of the car into a very small area (btw; a single pinch point is strong enough to support the ENTIRE car so crushing the point will NEVER happen) but still well within tolerances.

Since shops lift cars at four points simultaneously, each location bears less weight than when one jacks the car up at a single point. The car will be fine. Shops lift all cars this way.

Not exactly the entire weight of the car; more like (some fraction more than) half the weight, and then only if you jack the car up high enough to get both wheels on one side off the ground.

If you jack the car up at home once or twice every few years, you should be OK, but NEVER is a long time :) . Jack a car up enough times without a proper interface to the door sill and the door sill WILL be deformed.

Many thanks to drees, Dave and Andy for your replies.

I managed to get the wheels rotated today and they did use the pinch weld Jack Point positions. They had a circular pad with thick rubber which absorbed some of the pinch weld. All's good now!

Some considerations why I decided to go this route instead of D-I-Y: Wheelworks has a coupon for $39 lifetime- unlimited wheel balancing, unlimited rotations and tire repairs. This was the most optimal option for me since they are just located 2 minutes from home.

Incidently, the cost of purchasing both jacks needed for D-I-Y cost more than paying for the service.

Whilst they had the car up, I managed to also get a good look around under the car and inside the wheel wells.

For those looking to jack up their Leaf, I suggest getting hockey pucks and cutting slots in them. I used 4 hockey pucks with slots cut in them to lift my Leaf on a hoist using the jacking points. For the best fit, the slots are different widths between the front and rear (I am traveling and cannot remember which are wider). I keep one set with the hoist and I am planning to make another set to carry in the car to use with a floor jack or to offer to a tire shop.

That's a good idea as well because I have seen some folks in other car forums make them out of ice hockey pucks.

A company that sells a similar item is http://www.purems.com/product.php?II=833" onclick="window.open(this.href);return false;
but at $22 a piece.... Ouch!!!

I found a local hockey sport shop and bought 10 for $1 each after not finding them in stock at department store sport shops which listed them for something like $5 each on line.

I 3D printed a set at home. Has cut-outs on the bottom for the top of the lift and my jack stands. Work great!

Thanks for sharing that. It's very interesting that 3D-printed material is sturdy enough for supporting 900+ pounds...
