As mentioned above all 1st Gen cummins 2wd trucks have the 4000lb front axle, the 4wd is considered a 4500lb front end.

When I converted from 2wd to 4wd I tried selling the spindles and such, but can't recall if I sold them or not, if not I would have kept the nuts.....I will go check my bucket of misc large nuts.

 

These should be the right ones?

You could try car-part.com...they link 1000's of junkyards.

 

No luck from my big bolt bucket....

 

you looked in the wrong bucket...you said "Big Nut bucket....or you're saying you don't have Big Nuts....

 

My truck is a 1990 D250 with 2WD. 4k front.

 

[QUOTE=maybe368;3344978]I believe that all of the cummins equipped trucks had 4000 lb front suspensions, but that may be only for the 4x4 rigs. Is your truck a 4x4? Please fill in your signature so that we know what we are talking about..Mark

I am not sure what you mean by filling out the signature below. I am still rather new at this. My truck is a 2wd. D250.

 

Top of the page, left hand side, it says "user cp". Click on that. Go down the left side to "signature"

Fill in your trucks info. It makes it easier for anyone here to respond immediately, vs asking time and time again, " what do you have"

 

Yes, all the diesel 2WD trucks got the 4K pound front axle. Some 350 gas trucks would have had that available also. Some 350 B vans may also have that.
