Jacking points - for trolley jacks.
Posted: Mon Jun 18, 2018 5:07 pm
Just out of curiosity (because it is something I'm already doing) what are other people's preferred jacking points for trolley jacks at the front of the Marina? At the rear I just use the diff, but usually spread the load on the casting with some wood or a rubber pad. At the front, for years I've used the collection of plates that form a triangle where the tie bar mounts at the front, because they are thick metal and look like the strongest point at the front, but I've never been 100% happy with lifting on the edge of a plate. Again I used a rubber pad to protect the metal from the cup on the trolley jack, then I place axle stands under the flat part of the chassis between the tie bar mounting and the lower suspension arm mounting.
The reason I ask is because I've just spent an hour in my tiny lock-up, in cramped positions, because I'm getting new tyres for my Marina tomorrow and prefer to put the car on axle stands and take the wheels in my other modern estate car, rather than let some oik stick a trolley jack under my Marina. In the early 80s when I had my white one when I was a teen entering my early twenties, I got conned into having some new lever arms fitted when I went for an exhaust or something, and one leaked, and when I went back, the guy jacked the front of my car up on one side with his big trolley jack and the suspension dropped, and the tie bar was catching the side of the trolley jack cup and was bending. He gave me some bull about not being able to tell if the shocker was leaking or not because it was covered in sh*t, (which was because it was leaking) and then I just wanted him to drop my car down and get the hell out of there. Another time, but I can't remember who it was, somebody jacked the car up using the sump, putting the jack cup on the steel plate between the sump pan and the auto transmission, so the weight of the car was effectively being carried on the engine mounts. It isn't like there's a nice cross member on the front of Marinas to jack off. I'm sure plenty of Marinas and Itals go to tyre fitters and get jacked up without incident, but i've had that many old cars with wavy subframes and dented outriggers that I personally don't trust them.
