I'm thinking that the early bushes wore out fairly fast replaced by a steel one?

Ford ones are not critical, and I do have a press, so does every truck bush have the steel bush with bronze sleeve in them or doI just opt out of the bronze inner type bush????

Hi Ian,

I dug out the front spring repros I bought all those years ago. See attached.

The paperwork listed them as early F100 bushings.

PM me if you would be interested in them. Happy to pass them on for a lot less than what I paid for them if it helps someone out. They are just sitting on the shelf doing no one any good.

You would need to drill the grease access hole to the grease groove and ream the liner a slight amount for just a small clearance fit as Lynn mentioned. Didn't try it myself but perhaps a wheel cylinder hone would be enough to take out a few thou to make a good fit in lieu of an adjustable reamer.
Dimensions are:
ID: 0.740" OD: 0.998" and length 1.970" Slight size variations between all.

Hope this may be of some help.

Cheers,

These are the front spring bushes - For people just reading the thread. Yes Jacques, they are close to my measurements. the originals have no split to slide into the spring eye.

Traditionally I have used a large pry bar and spread the 'eye' slightly to allow the bush to be pressed in nice and gently. Otherwise too much pressure will squash the end and you cant get the bush centred. I did that the first time I ever pressed in a bush into a spring.

Oh and Yes the best way to 'ream' the eyes is with a brake hone. You will do about 6 eyes and then its time to buy another hone but way cheaper than a reamer!

The one I have pictured I just wiggled it out of the spring eye. It wasnt that clean though!!

Cheers Ian, Pm Sent Jacques.

Hi Ian,

Here's an original Ford stamped bushing with a split. I saved one as a sample after renewing mine. From memory all four had the split in them. I have also seen the ones without a split like yours.

Any reason for the split? Perhaps if the bushing is made with a slightly larger OD than the spring eye this ensures an easier fitting, but still a tight fit in the spring eye? Perhaps it is a later change to make assembly or repair easier?
Any suspension experts here that can answer that question.

I did mine so long ago I cannot remember exactly how it did them but I think I used a bit of threaded rod and washers and a socket to pull them into the spring eye. I have used that method on a few occasions as a puller. Don't remember any great issues doing it. Spring eyes were free of all rust and I would have greased them. Only need a bit of rust to lose a few thou clearance and cause problems with tight fits.
