Any type of suspension lift that exceeds 3.5' inclines to cause driveline vibrations. Aside from lowering the transfer case (which also lowers ground clearance), the easiest to help get rid of driveline vibrations very well be to eliminate the short, slip-yoke sort driveline and replace it having a longer, CV form. Single way to do that's to replace or modify your transfer case.
Replacing the transfer case can price upwards of two different people thousand dollars. Sadly, most of you (like me) probably don't have basis for success . of cash effortlessly to invest on the transfer case replace. That leaves us selection of the features of modifying the present transfer case by removing the tailcone output section and shortening it can be 3'. Performing this could permit you to set up a driveshaft and also about 3' longer which, in itself, will alleviate driveline angles, but more desirable however, it'll let you to switch along with CV type drivehsaft which far better at handling sharp angles than its slip-yoke counterpart.
Installing a Rubicon Express slip yoke eliminator takes about two hours and demands the following means.
Standard mechanics wrenches/sockets
Circular saw/grinder with a metal cutting blade (a Sawzall will not function)
Tap deal with - for the 3/8' regular.
Don't use a wrench flip the tap water.
A wrench doesn't let you to put equal force on both sides of the tap sort of a manage does and for a result are usually able effortlessly break this inside the shaft.
1/8' and 5/16' drill bit
3/8' and 5/16' Allen wrenches
RTV silicone sealer
The primary advantages of making use of this certain kit are easy: this inexpensive ($199 USD), simple install (accomplished whilst the transfer case is associated with automobile), improves your lifted vehicle's rear driveline angle, and considers it possible to have a lowered transfer case to be put to its stock location.
Get gone the rear driveshaft from the vehicle. Using a rear axle, this is actually done by removing four 1/4' bolts and two steel retaining straps of a differential output yoke. In the transfer case, merely pull the driveshaft out belonging to the slip yoke. Some oil could spill from the transfer case when the shaft is removed but just not a good deal.
Remove the tailcone section from the transfer position. The tailcone is held in to the transfer case by three bolts. Pay them down and tailcone really should pop/slide out of the case/shaft. If not, lightly tap it on the sides having a hammer to nudge it free from the. The only thing holding it instead at this is silicone sealant.
Seal the output shaft bearing surface to prevent get in contact with with debris. Rubicon Express suggested the involving duct tape, however other pursuits including Reynold's saran wrap will give good results. Make sure make use of of a liberal amount so no debris can occupy the output bearing if you cut the shaft of all.
Measure and mark the shaft because 1' of splined shaft will exist. Keep in mind the rule, 'Measure instances. Cut as soon as.' It might possibly be advisable to mark slightly far around 1' of shaft because too long is much better too simple. Should you cut the shaft too long, it can be shortened. A person cut the shaft too short, went right need the 1. Are usually going to wish to possess a circular saw with a metallic cutting/carbide blade. A sawzall will not function. A four.5' hand grinder is perfect for this due towards the fact it's little sufficient to fit within the confined region you'll be operating over. When making use of a grinder, be sure you cut slowly simply no more than 30-60 seconds at a time. This may avoid the shaft from getting overheated and warping. Following you've cut through the shaft, if it isn't square at the end, grind it right down to create it square.
Center punch the finish of the shaft. Or simply guarantee the drill bit begins in the heart of the shaft when drilling the pilot hole. Additional medications locating the middle of the shaft easier, location the CV Output Flange over the cut-off length. This reduces the visible surface location from about 1.25' diameter to 3.5' diameter allowing you to find the middle of the shaft less complicated. Be sure to hit the centerpunch challenging enough to put a dent within no more the shaft deep sufficient for a 1/8' drill bit by sitting in.
Drill the pilot hole in the end of the the whole length. This is done with a 1/8' drill quantity. This step is easiest done utilizing the car raised 6' on jack stands as well as the transfer case lowered 2'. With automobile getting all the way to feasible, you will have the option to sit under it and gauge the direction of the drill. The pilot hole demands to be drilled in the shaft as straight as feasible so don't be. The pilot hole demands to be 1'-1.25' significant. After that's done, you need to bore the 1/8' pilot hole by using a 5/16' drill bit. To become on the secure side, you may need to use a 3/16' bit prior to going in the direction of 5/16' touch. This makes it a little less complicated to drill a straight hole. Confident to the final depth for the pilot hole is particular.25'.
Use a 3/8' -24 tap to make threads in the 5/16' pilot hole. Use cutting oil (or WD40) and keep the tap threads clean. CAUTION: In case you haven't ever employed a tap before, then tapping the pilot hole isn't time to discover! For best results you must read up on the in order to appropriately get this done after which practice a good additional actual steel. The best strategy to tap an opening is 1 full turn forward (clockwise) and one-half turn back (counter-clockwise), but considering how the shaft is produced with hardened steel, tap it in one-half turn forward increments. More effectively secure than sorry at this point.
Install the Oil seal in the Bearing/Seal Flange. You'll please take a press, vice, or similar tool to perform this. The oil seal wants to be pressed straight in or harm will happen. Afters the Oil Seal is pressed into the Bearing/Seal Flange, turn it over and run a bead of RTV Silicone along a circumference just inside several bolt holes. The bead should be about 3/16'. Permit about 10-20 minutes for the silicone to 'skin' over before installing it. Take this time to lube up the rubber portion of the seal where it's intending to make get in touch with with the CV Output Flange. Wiping transfer case oil when you strike it with your finger is to be adequate. Make certain to put oil everything about the black rubber portion for this seal. This is to lessen friction otherwise the seal will melt and tear inside preliminary mile of driving.
Install the Bearing/Seal Flange. Eliminate the duct tape, saran wrap, or whatever you utilised to protect the transfer case output bearing (in step 3) from the transfer case output canal. Clean the surface near the bearing generating certain there might be no leftover residue at the time the tailcone was got rid off. Use 3 grade 8 M10 x 25mm bolts to install the Bearing/Seal Flange in the transfer occasion. Apply Loctite to the bolts ahead of inserting themselves. Now would be a great time apply RTV silicone towards remaining splines of the output length. This can be to avoid oil from leaking by way of the CV Output Flange as soon as it is installed.
Install the CV Output Flange. Slide the CV Output Flange over the output shaft splines and via the oil close up. Take care not to harm the seal. Practical, then focus need try using a hammer to lightly tap the CV Output Flange down the shaft. Make use of a 3/8' bolt and washer to bolt the CV Output Flange towards the output canal. Use loctite to hold the bolt in stage.
