f-150 misc. questions.
I have a 95 F-150. I JUST LIFTED IT 6" WITH SUPERLIFT FRONT SPRINGS AND REAR BLOCKS. PROCOMP SHOCKS AND PITMAN ARM. TROUBLE IS I NOTICED FRONT RIGHT AXLE IS TOUCHING HOUSING WHERE IT PASSES THROUGH ON ITS WAY TO HUB.IT JUST BARELY IS TOUCHING BUT ENOUGH TO CONTACT WHEN ENGAGED IN 4x4. ALSO CLUNKING NOISE UNDER TRUCK WHILE ENGAGING AND DISENGAGING CLUTCH. SOUNDS LIKE TRANSFER CASE HAS PLAY. LOTS. ALSO IN 1st GEAR IF I PULL OUT QUICKLY, SLIP YOKE OUT OF TRANSFER CASE CAN BE HEARD RUBBING ON EXHAUST SHIELD. ANY IDEAS ON THESE THINGS ? ANY HELP APPRECIATED..................ALOHA

The RF axle rubbing the housing is probably from one or both of the front suspension drop brackets not being properly aligned, or maybe bent. Did you use radius arm drops, or extended arms?
A clunk is most often a bad U-joint (and you can expect them to wear out faster with the lift), but after adding rear blocks, there's also a good chance that the U-bolts are loose & the axle is rocking under the blocks.
The slip yoke problem sounds like a broken transmission mount on the crossmember between trans & t-case.

thanks for the reply. I'm using ext. arms, so I relocated front R-arm brackets. the bent drop bracket sounds good, as I got this second hand. as for the u-joints. I replaced both rear. not the front. I heard from a friend that the rubbing on the exhaust could possibly be slip yoke worn and causing wobble until higher rpm is reached. only way to check I guess would be play stunt man and hang under truck at speed. I haven't gotten to the trans/t-case mount yet, but pretty soon. the clunk was occurring before I did the lift. I already changed clutch/pilot bearing/slave/throwout with out luck. Recenly got a donor truck. took out transfer case and found backlash REALLY low compared with my unit, so I figured that might be the cause. I wont' know for sure until I swap the unit and disect the other. thanks and will be in touch..........aloha

To check the slop in the slip splines, just get under the truck with the t-case in N and the park brake set. This relieves all the load from the d'shaft. Then see how much play you can get by pushing, pulling, & twisting the slip joint. If it's enough to see, it's too much, but maybe not enough to be a problem.

I had a clunk in my drivetrain and after changing 1 bad u-joint, I figured I had it licked, but still there. After some searching and and being a "stuntman", I found that it was my T-case mount. I figured the rubber mount was broke, so I went and got a new one and upon install I found the mount was good. The 2 mount bolts through the crossmember and pulled through. The crossmember had broke 2 perfect washer sized holes right through. After some fab work and welding, problem fixed and no noise, and I also noticed my stick shift didn't move as much (side to side) anymore.

sorry so long to reply. I did not do any drive shaft changes yet. I am in the process of swapping in a C-6 trans which will require a different length shaft anyway. I narrowed the clunk issue to the rear end. backlash from a previous install. I got under the truck with a person in it. and they put it in forward and reverse while I observed shaft rotation. it seems the transfer case engages correctly, but there is a slight delay before the wheels turn enough to produce a clunk when tacking up slack. I am in the process of swapping the 8.8 out for the 9" today if everything goes well....aloha
