Post Hydraulic Trolley Jacks

Back when I had my Indie Shop I used only Hein Warner jacks and they'd last about 15 years before begging to leak or slowly drop .

Back then at least once a year some scruffy guy would come by and overhaul them for about $100 in a couple hours .

My Son finally convinced me to by a Chinese 3 ton trolley jack and it lasted close to 20 years, stored underneath an old vehicle parked on Concrete, I'm pretty sure he's still using it, I bought a new 3 ton Harbor Freight one on sale 15 years ago and so far I've only needed to add jack oil to it once .

Maybe I'll try the cute all aluminum low boy quick lift ones he likes for his racing .

As mentioned, never, EVER fail to use safety stands ! not even for changing a tire .

Once you see a vehicle fall when a jack fails, you'll understand why this is so important .

I'm sure there are pictures on the internet of heads popped like rotten tomatoes from folks who 'only needed a minute' to work sands stands .

Cars can fall off of jack stands too. I recall reading about one of those on a BMW board a few years back.

The key is to have a primary and secondary support, at minimum.

The good thing, at least with the w123, is that if the tires are left on, it's relatively high up off the ground to begin with. That's not justification to avoid protections, more of a little peace of mind when under a car like this versus some others.

Doesn't mean no backups...

Post Safety Knows No Season

Only improperly set vehicles can fall off safety stands ~ I always give the car a good shake after they're set before going underneath .

Jack stands themselves can also fail. Always safety block. It really only takes a minute.

Where it can take months to get better or even result in death otherwise. I am not the squeamish type but at the same time there are limits. To my risk tolerance.

Another consideration is most members on site are do it yourself types. Some with limited experience may put a jack stand in the wrong place. We all start somewhere when working on cars. Very tough area to lean a lesson from.

Love that old-timer! I've had a Harbor Freight 2 ton for at least 25 years with no issues and just bought a HF aluminum racing jack that I made a box for and carry it in the Dodge PU (my DD) so it's always on hand. I'm still looking for the hydraulic jack races to try it out......

No more often than a home owner jack is used, they will last practically forever as long as the jack is lowered until it bottoms before storage so that the rod is protected. Unlike industrial hydraulic rods on forklifts, tractors, etc... jack rods aren't chrome plated, so they rust up almost instantly. Rust pits cause leaking and wear the seals. Also make sure not to ding the rod for the same reason, dents in the rod will damage the seals. I have a HF I bought in the early 90s that still works perfectly, a Blue Monster low profile I bought used that is over 20yrs old and a big long 50yr old Weaver 2ton I bought for $50 off Craigslist. The Weaver leaked, but I was working as a machinist at a chrome plating/hydraulic shop. Chromed the rod and put new seals in it. It'll lift over 30". Combine that with heavy jack stands and my transmission swap on the ground wasn't too bad.

I like the Euro idea of driving over a pit. My version is to make stands that are made from three 2 x 12 boards 30" long, screwed one on top of the other.


I use my jack to life under the engine cradle or the rear axle pig and then set the car's tire(s) underneath.


When the tire is sturdily standing on 2x12 boards 5" above the ground, you can't go anywhere. Especially if you are in park with the brake on and chocked.
