Links for rear shock absorber 52 4AD

Post by wmcvey »

There are these two links that go to the rear shock absorbers and I think the same two links go to the front tie rod ends.
Would anyone know what other car there off of ? I have the links, it's just the rubber inside of them is starting to fall apart.

Also any info on transmission mounts, again the rubber parts are too old.

I may have info on the links, I will check

For the rear mounts, there is a rubber door stopper that works "almost" perfectly, you have to round off a little bit of the top to fit in the cups, I should have the part number for it. DO NOT buy the one below until I verify the part number... but to give you a idea of what it looks like. I will find the part number. I think the one below is wrong but it could be made to work, as I said, I had the part number at one time, should be able to find it for you

I used a modified universal rubber from Kramp, important is the shore, and the measurements.
The modification is just remove the standard welded nuts on the outside.
The engine on the picture is the standard nine for the 4A

The two mounts I'm hunting for are the tranny mounts, not the motor. They're on the back end of the transmission, or maybe called the gearbox mounts.
Any help on those ? But come to think about it I'll need to check the motor mounts also.

That would be very helpful thank you. These rubber items should work on the two links on the front end as well if needed ?

When I rebuilt my rear shocks, I was unable to find suitable links or rubber ball inserts, so I purchased inexpensive low precision heim joints and long coupling nuts and made up my own links. Sure, the heims are exposed to dirt and moisture, but at the low annual mileages I drive, those links will outlive me. Not issues with harshness, btw.

Any luck with finding that part number ? Thanks, Bill

I repaired my rear tranny mounts on my 4ADT and took some photos of the process. I will try and dig them out. I recall someone once saying that there was a Jaguar model that used the same part. The bonded-in nut is not the best design, especially where there is a lot of oil leaking around the area!

There were many British cars that used those lever arm dampers and the links came in many versions. Check out those used on the Morris Minor to start with.

Hope that helps..

Unfortunately, I did not find the thing. I found my book that I had interchange numbers for the 4AD but it did not include that item, I thought it did.

I noticed this post is about 6 months old but may be able to assist on both the rear gearbox mount issue and the rear suspension/sway bar links for the 4AD. I could not source new links anywhere when I was looking for them around 2015. I modified modern links that are found on many makes these days (I think mine were off late model Hyundai sedans. The shaft had to be shortened so I cut this and put a threaded sleeve and lock nuts over them to get the correct length. The ends are a perfect fit into the existing link mounting holes. The best part is that if the flexible joint ever gets sloppy, new ones are on many modern cars. I will take a photo once I’m back home and post it up in case this is still an issue for people. I’ll also try and photograph my gearbox mount modification-I was not able to get a new pair of these mounts anywhere I searched at the time but have come up with a very satisfactory substitute.

Above is a sketch of the modified rear gearbox mount I made for my 4AD. Coming up with an alternative was a necessity as I could not source replacements at the time I needed them. It can use the original mount backing plate and new grommets that the mounting horns of the gearbox fit snugly in. The beauty of it is that if the mounts chop out, new grommets are easily sourced.

Suspension Link 4AD.jpg
Above is a photo of the new suspension/sway bar links I made for my 4AD. Its a bit difficult to see from the photo but the link between the universal ends are male threaded with a female threaded tube over them. This allows the length to be adjusted easily and locked with lock nuts when the right length is achieved. These links are on many modern cars and it is just a matter of cutting the modern link and threading it to the rough length required and making a corresponding tube and lock nuts to suit. I hope this is useful!

Regarding the rear tranny mounts, Dave Green, Meisterwrench and NASOC PArts Guru suggested this option with a bit of modification required:

The front engine mount ids available from a store on eBay based in Australia BTW.

There used to be a source for the rubber inserts for the shock links and I redid mine that way, but they were sourced by Bill Haverly in the UK and, sadly, Bill passed away some years ago now.
