UJ problems

I have an F150XLT(1972), with a large body and suspension lift on it(as purchased) and it runs 40" tyres. But I keep blowing UJ's due to the angle on the propshaft. I am sure I am not the only one running oversize tyres, is there some aftermarket product that will solve this ?? Or does it just come with the territory???

I dont know who, but sombody makes spacers to point the axle up to decrease the pinion angle. I have heard of lift blocks that come like this but have not seen any. I have had people tell me to put a carrier bearing in somewhere, but I think that is more work than what it is worth. What kind of U-joints are you using? I tried el-cheapo's and ones that were supposed to be for hardcore off-road use from the parts stores, and they just dont cut it. I went to a driveline place and started using spicers and they last 4 times as long.

UJ problems

Just to add some to the above, do you have a cardigan(double u-joint)at the tranfer case? If you do, the rear axle should be shimmed with tappered shims made for this purpose from a spring shop or 4x4 shop. They come in several different degrees, the rear should be a straight as possible with no angle at the pinion when using this type of set-up. If you do not have a cardigan, then you might consider havin' one build with this on it. Without, the angle at the 'case and the rear must be the same to cancel out each other. If they do not match this will cause bad vibes and a very short life no matter how good the U-joint. Might also look into upgrading to 1 ton yokes, this would reguire new driveshafts(propshafts)to match the yoke, but, it can and has been done. This will give you about the strongest set-up you can get. Also, make sure the propshaft slip-joint is still in good shape, there should be no side play at this point, if there is it must be replaced or refitted with new splines. Chuck P.

It does not have a cardigan end at the transfer and the angles are different so I presume that's what is causing the big problem. I have full hydraulic suspension so the shims are a no go, but I like the idea of the 1 ton yokes, where abouts would I be able to mail order these from, as I am from the UK.

Many Thanks

Im just curious, I noticed you said a 72 F150, Ford didnt introduce the F150 till 73 didnt they? I could be wrong..But this is first ive heard of one..BUT the reason im asking is on my 72 F100 we have noticed a number of later model F150 parts which caused a few problems(mostly front end parts) Excuse my ignorance :P

It's an import obviously, and it's plated as a 72/73 F150. But, it has a F350 rear-end, a 460 engine out of God knows what and all manner of other little cowboy additions and trinkets. So I presume it's 73 who knows????
