| Jacking with a High Lift Jack |
|
Can someone explain their technique for jacking the rear of the vehicle with a high lift jack? On the occasion that I tried it the whole rear of the truck seemed about 2 metres off the ground before the wheel came up enough to change it. At this stage the vehicle was so unstable that the slightest lateral force would have tipped it sideways off the jack. I can't recall what suspension setting I started with either.

Sounds like my experience of a high lift.
Don't know a way round that. 2006 G4 Challenge Support Vehicle

High lifts are unstable with any vehicle. Use them with care. I have an air jack which is better.

High lift jacks ARE NOT for changing a wheel with! They are intended for recovery purposes only and are not stable enough for that use.

How did you get a HiLift on the rear bumper without crushing the plastic? Do you have a Kaymar bumper?

Lex, high lift aside... use off road height, switch off and leave a door open. Should stop her stretching her legs.

Thanks for the input fellows. With regard to the reply by simonmd saying that high lift jacks are designed purely for recovery purposes what a load of garbage. Over the last 20 years I have changed several wheels using a high lift jack, mainly on Nissan/Toyota trucks which don't have the same wheel travel that we have with our Dicovery's. Providing the jack is located properly and wheel chocks are used it is perfectly safe. Sure you can use the jack as a de-facto winch for recovery providing you have the rest of the day free to do it . I stress again the importance of properly locating tha jack tongue either in a Kaymar slot or dedicated high lift jacking attachment. TDV6 HSE Zambezi/Tundra

Indeed, but the way it was described, useing the jack on the rear of the car, is NOT the way to change a wheel. Lifting at the front or rear is a recovery technique to get a grounded vehicle out of a hollow, etc. If a HLJ is to be used changing a wheel, then it must only be used at the side so the wheels on the opposite side remain in contact with the ground. Then it is perfectly stable although wheel chocks should still be used. For serious offroaders, side rock slider bars can be fitted allong the sills with built in HLJ mounting points for this purpose.
