Bushing Identification (front)

Unread post by ndcctrucks » June 14th, 2017, 10:52 pm

Hi All:

I have purchased four pairs of front bushings, but they do not have the part numbers on them

Image

As you can see, they are different.

One is an 8342300 and the other is an 8342304.

Can anyone identify which is which? For clarification, the one on the left has a higher crown by nearly 1/4".

Thanks!
-Ken

Appears to me to be different molding techniques. The rubber is bonded to the metal differently at the bottom of the two meaning different manufacturers probably. Get a caliper and measure the diameter of the control arm and the bushing and also the length. If one of the old ones came out with any measurable parts check that also. It is not the rubber sticking out the ends that does the work, it is the stuff on the inside. You could trim that one with the bigger rubber end down if need be to fit in the bracket as long as the metal part is the correct fit and the bolt hole is correct.

Ken,
I hope you haven't removed the old bushings from the top suspension arms!
You will need to carefully compare the old bushings with the new ones..... they both fit the top arm but go at either side of the arm and shaft assembly.
Unfortunately the TM doesn't give the dimensions of the bushings but if you look closely at the TM (TM9-2320-218-34-1, page 86), it looks like item-8 (8342300) is the tall bushing and item-10 (8342304) is the small bushing. Compare with the old ones to make sure.
Ken
Kind regards....
Ken

Always wanted - Details and pictures of M416 Trailer data plates & M151 data plates & body-tags for my research. Thanks!

I would think that if one is longer than the other than the inner steel bushing is also and it is only going to fit in between one of the sets of brackets.

One is squeezed between two washers, and one is not. That appears to be the difference.

Ken:

Thanks! The copy I have is of poor quality, and I could not see the difference in the illustration.

Yes, all of the old bushings have been removed; removing the washers did not show any difference to me. Rapid work was done to take advantage of free use of a sand blaster cabinet.

When I get this sorted out I will post.

Thanks All

I just did all the bushing on my front suspension. The manual says about long and short bushing and where they go.
After going back and forth I simply put the one with the longer rubber as the "long" bushing and the other one as the short.
I was confused at the beginning but the pressing in worked well and also the assembly.
Good Luck!

Hi guys,
I am about to replace the bushings on my front suspension arms. SO is it okay to use four of the same bushings top and bottom, as I can only locate four of the 'long' bushings, washers, bolts and nuts from a supplier over here (UK)?

I have seen a US-based supplier is offering the complete kit of bushings front and rear, and that includes 'short' and 'long' bushings for the front suspension arms.

Thanks

I would be careful about using the wrong lengths of them. I always say that there HAS to be a reason the parts number is different for different bushings. There HAS to be a reason they made them a slightly different length.
