## Questions & Answers

**Q: Looking at the picture the grease nipple is in the wrong place and would not allow the wheel to fit on the hub.  Am I seeing this correctly?**
A: HI,
Generally, 4" PCD wheels have a corresponding cut-out in the wheel to go over the grease nipple. There are some exceptions and variations if your wheels came from an old car. However all 4" PCD trailer wheels will all have the cut-out.

If your wheels don't have a cut-out, it's probably best to recheck your measurements. You have to be pretty accurate when measuring - 4" PCD (101.6mm) wheels are commonly confused with 100mm PCD wheels because there is only 1.6mm difference. 

This is just a general guide, but if you send us a send a direct Amazon message we can give you some more specific advice.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Exactly what I wanted.
*by P***N on 15 August 2019*

Fitted these suspension units the day they arrived, perfect fit, trailer up and running again, good quality did exactly what I wanted them for, highly recommend this product and suppliers.

### ⭐ Poorly made
*by P***N on 26 June 2024*

No split pins for the bearing nuts.Not enough clearance between grease nipple and hub body to get a grease gun on.Dust cap does not fit---too large, won't fit into the bore.Incorrect wheel nuts.Have now purchased hubs elswhere, just praying the actual suspension units are ok.

### ⭐⭐⭐⭐⭐ Great fit
*by D***S on 12 August 2022*
