Transfer case noises indicate a problem and shouldn\u2019t be overlooked. The transfer case is an essential part of a four-wheel vehicle as it delivers power to both the front and rear axles.<\/p>\n\n\n\n
Driving a faulty transfer case will only lead to further damages, which will pile up the potential fixing cost.<\/p>\n\n\n\n
Here, we\u2019ll discuss what causes the transfer case noise when accelerating and how to fix it.<\/p>\n\n\n\n
The location of the transfer case can vary from vehicle to vehicle. In most vehicles, you can find it between the front and rear axles and the transmission.<\/p>\n\n\n\n
In some cases, the transfer case may be visible from underneath the vehicle. You have to look for a square-shaped part that\u2019s considerably large. It connects the front and rear driveshafts.<\/p>\n\n\n\n
We highly recommend referring to the owner\u2019s manual of your car for more information on the location of the transfer case. However, it must be noted that you shouldn\u2019t undertake this without proper technical know-how.<\/p>\n\n\n\n
If you can\u2019t put the vehicle\u2019s components back together, you won\u2019t be able to get it to work. Ultimately, you\u2019ll have to tow your vehicle to a mechanic. So, if you\u2019re not confident enough, just take it to the mechanic straight.<\/p>\n\n\n\n
Here, we\u2019ll describe the process of fixing a faulty transfer case step by step. So, stick with us.<\/p>\n\n\n\n
Start by removing the driveshaft at the rear end. You need to spray some penetrating oil on it before removing it. Also, mark the conjunction of the shaft and the rear differential.<\/p>\n\n\n\n
This will help you put it back in place, especially if you\u2019re doing this for the first time.<\/p>\n\n\n\n
Usually, four screws connect the driveshaft and the rear differential. Unscrew them with a wrench but keep the bolts stored safely. Once the bolts are removed, put a bucket underneath it.<\/p>\n\n\n\n
Now, pry the driveshaft to remove it.<\/p>\n\n\n\n
The housing of the tail shaft is secured by bolts that you can remove with a wrench. Make sure to place a bucket underneath to collect any fluid.<\/p>\n\n\n\n
When removing the shaft, you may find a snap ring. It also comes out with the tail shaft housing sometimes.<\/p>\n\n\n\n
Now, take a close look at the condition of the ring. If it looks broken or worn out, then you need to replace it. A broken snap ring usually leads to vibration and noise. It\u2019s very common for them to break under stress.<\/p>\n\n\n\n
The best fix to this would be to remove the snap ring completely. Get a locking ring instead. These rings are much better in terms of both durability and performance.<\/p>\n\n\n\n
To install the locking ring, simply locate the groove where the snap ring was supposed to go. There\u2019s an outer lip at the end of the locking ring which you can fit there.<\/p>\n\n\n\n
Once you\u2019re done installing the locking ring, it\u2019s time to reinstall the driveshaft. While doing so, just make sure that you face the weep hole on the seal downward. Also, wiggle the U joint to make sure it works properly.<\/p>\n\n\n\n
Also, clean of any grime on the rear differential. This will make the component last longer.<\/p>\n\n\n\n
In most cases, you can replace the transfer case fluid easily. However, you have to remove the metallic plate that\u2019s protecting the transfer case from any external impact.<\/p>\n\n\n\n
Once that\u2019s done, unscrew the fill plug with a drain pan underneath. Check the fluid in a transparent container to see if it\u2019s contaminated or not.<\/p>\n\n\n\n
If it\u2019s contaminated, then you have to replace it. But first, you need to flush out any remaining oil. Pour some more oil into the case to drain the old oil out with the new one.<\/p>\n\n\n\n
Then, proceed to fill the transfer case with new oil. Fill the transfer case, screw the fill hole bolt, and put the metallic shield back into place.<\/p>\n\n\n\n
